In a game that was full of mistakes and mental errors, Matt Hasselbeck was not exempt from the list of issues that will need to be examined after the game.
Hasselbeck completed 20-of-35 pass attempts and threw for 194 yards, one touchdown and one interception in the loss and took a number of sacks while holding on to the football too long.
While he may not have been the primary problem today, Hasselbeck's lack of velocity and inability to get the ball down field was once again on display as the Titans quickly fell behind and were unable to ever gain any momentum.
Third quarter: Hasselbeck engineered a touchdown drive on the Titans first possession of the second half to bring the Titans within three possessions, but stalled on the Titans next drive as the Titans continue to trail big.
Halftime: It was a very difficult first half for Matt Hasslebeck, who has thrown an interception that was returned for a touchdown and has faced constant pressure from a punishing Bears defense.
Hasselbeck has struggled to locate open men as the Titans offense as a whole has shot itself in the foot time-after-time.
Going to need a heroic effort from Hasselbeck if the Titans hope to make this a game in the second half.
First quarter: A big pass play to Kenny Britt on the Titans first play from scrimmage was quickly negated by a Britt fumble that handed the ball to Chicago.
Hasselbeck's day thus far has been highlighted by a terrible pass that was intercepted and returned for a touchdown by Brian Urlacher.
Starting his fifth consecutive game in place of the injured Jake Locker, Matt Hasselbeck will look to right the ship after leading the Titans' offense to just 13 points in an overtime loss to the Colts last week.
Hasselbeck enters this week completing nearly 64 percent of his passes and has thrown for six touchdowns and four interceptions on the season.
Facing a tough Chicago Bears secondary, Hasselbeck will need to protect the football and have some early success if the Titans hope to be in the game late in the second half.
The Tennessee offense managed to put 20 points and 333 yards on the board, however turnovers and third-down failures plagued the offense throughout the game.
The Titans finished the contest with five turnovers and converted 3-of-12 third downs, failing to establish any sort of consistent success throughout.
Chris Johnson's 80-yard touchdown run in the fourth quarter highlighted the Titans running back's 141-yard effort.
Third quarter: The Titans were able to put points on the board and avoid turning the football over, so it was certainly a step in the right direction after a miserable first half.
Tennessee has found itself out of the game, but could build a bit of momentum heading into next week with another touchdown drive or two.
Halftime: The story of the Titans offense in the first half was pretty simple: turnovers.
Tennessee turned the ball over four times, leading to 21 points for the Bears, and have been unable to stay on the field long enough to keep the team in the game.
The Titans piled up 145 yards of offense in the first half, with Chris Johnson rushing for 40 yards on 11 rushing attempts.
First quarter: The Titans offense has really struggled to move the football since an opening 23-yard pass play.
Tennessee needs to start converting third downs and must avoid potentially drive-killing penalties that have already plagued one drive.
A trio of first quarter turnovers has plagued the Titans offense as they have failed to stay on the field and has repeatedly put the defense in terrible situations.
With a rejuvenated running game over the last five weeks, the Titans come into the game missing starting right guard Leroy Harris, while the rest of the offensive line is active but are all nursing minor injuries.
After talk of a potential trade request early in the week, it will be interesting to see if offensive coordinator Chris Palmer and Hasselbeck attempt to work Harris into the game early and establish him as a true threat as the Titans enter the second half of the season.
Chicago boasts one of the top defenses in the league, so the Titans will need to establish the running game and help take some of the pressure off the veteran Hasselbeck.
The Tennessee defense was repeatedly placed in poor situations and crumbled as the second half wore on, allowing 14 points in the fourth quarter in the rout.
Chicago piled up over 350 yards of offense and were able to consistently take advantage of great field position and convert once they reached the red zone.
The Titans were able to hit Cutler throughout the game but were often gashed when Chicago elected to run the football, as Matt Forte and Armando Allen combined for nearly 150 yards on the ground.
Third quarter: The Bears have been able to move the ball effectively and have scored 13 points in the second half to continue to build its lead.
The Titans defense continues to pressure Cutler but is beginning to wear down after spending much of the half on the field.
Halftime: Despite allowing 31 points in the first half, it's difficult to lay all of the blame at the feet of the defense.
The unit has repeatedly been forced into short fields and 14 of the points came on a blocked punt and an interception that were returned for touchdowns.
Chicago has just 136 yards of offense in the first half, but have managed to build a 26-point halftime lead.
First quarter: Although Chicago managed to put points on the board in the first quarter, that is through no fault of a very impressive
The Titans have shown some aggressiveness, sending more than four men a number of times, and have collapsed the pocket consistently in the early going, leading to a foul in the end zone and a safety to give the offense the ball back.
Cutler is having little time to scan the field and when he does, is finding little open down field.
Titans defense has been put in poor positions time after time and have not had a fair chance to keep the team in the game.
Despite some struggles with consistency throughout the season, Bears quarterback Jay Cutler pilots an offense that ranks eighth in the league in scoring, averaging 26.4 points per game.
The Titans' defensive struggles this season have been well-documented, as the team has allowed over 20 points in seven of its first eight games and sits in last in the NFL in scoring defense, surrendering over 32 points a contest.
However, the unit is coming off its strongest performance of the year last week, where they held the Colts' offense to 13 points in regulation and 19 points overall in the loss.
The Titans' pass rush, which has shown some consistency in recent weeks, will need to get to Jay Cutler throughout the game and not give him time to scan the field and beat the Titans downfield.
The Tennessee specials teams committed numerous penalties and had a punt blocked that led to a touchdown in a day special teams coordinator Alan Lowry will hope to forget moving forward.
Darius Reynaud was unable to get anything going in the return game as the Titans struggled overall.
Halftime: A long punt return, a blocked punt and a number of special teams penalties have all but sealed the Titans fate in this game.
Rob Bironas added a field goal late in the second quarter, but that remains the only positive in what has otherwise been a miserable 30 minutes for the special teams unit.
First quarter: The special teams play early on has been highlighted by a blocked punt that was recovered for a touchdown by the Bears and a long return by Devin Hester.
The Titans special teams has been responsible for a couple penalties and have yet to have anything other than a negative impact on the game.
The Titans have received a number of big plays from their special teams throughout the course of this season, and that trend will likely need to continue against Chicago.
After missing a field goal last week, Rob Bironas will look to rebound as the Titans will have to take advantage of every scoring opportunity they get against the top scoring defense in the NFL.
In the return game, Darius Reynaud will have to make quality decisions about taking the ball out of the end zone and look to set up the Titans with good field position at least a few times throughout the contest.
Very little can be said about the coaching staff when their team suffers a 51-20 home defeat.
The Titans did not look prepared in any facet of the game, and consistently committed mental mistakes leading to turnovers and penalties.
Mike Munchak will need to carefully examine the tape of this game and some changes will need to be made after the team's most embarrassingly loss since a 59-0 defeat to the New England Patriots in 2009.
Halftime: Any time you are trailing 31-5 at halftime, some of the blame has to be placed on the coaching staff, particularly when there have been so many fundamental mistakes early on.
Penalties, fumbles and a few missed tackles have not reflected well on the Titans preparation leading into this weekend.
First quarter: Titans have shown some aggressiveness but have also struggled to avoid penalties and mental mistakes in the first quarter.
Very little going right for Tennessee right now.
Titans head coach Mike Munchak and company will need to put together a quality game plan if they hope to get a win against one of the best team's the NFC has to offer.
With a seemingly disgruntled Jared Cook, it will be interesting to see if the Titans' coaching staff works him into the game early, as the Titans will need all of their receiving threats in the game if they hope to pass against a tough Bears' secondary.
Defensively, the Titans' defensive end duo of Kamerion Wimbley and Derrick Morgan have to get up field and attack Jay Cutler if the Titans want to keep Cutler, Brandon Marshall and Matt Forte out of the end zone.
