There are numerous teams that either have questions at the quarterback position, or are still trying to figure out who will be under center in Week 1 of the regular season.
The deeper we get into the preseason, the clearer the quarterback picture will become for the teams that don't quite know who the field general is going to be when the season begins.
In the second set of preseason games, we will see plenty of quarterbacks step up and solidify their hold on the starting job, but there will also be guys who play themselves out of a starting spot.
Here are thee quarterbacks to watch during the second set of preseason games not named Andrew Luck, Robert Griffin III or Peyton Manning.
Last season, Locker played in just five games, but the small sample size definitely allowed the diehard Titans fans to rest easy at night. He completed 51.5 percent of his passes for 542 yards, four touchdowns and zero interceptions to compile a 99.4 quarterback rating.
In his first preseason game of 2012, the former Washington Husky went 7-of-13 for 80 yards in limited time.
The Buccaneers don't have a great pass defense, so look for Locker to show why he was the No. 8 overall pick in the 2011 NFL draft.
If he can develop some chemistry with Nate Washington and first-round pick Kendall Wright, his transition to the starting role will be that much easier.
Tannehill lost a solid possession receiver when Chad Johnson was cut, but don't count on that hindering his progress under center.
NFL.com reports that Dolphins head coach Joe Philbin hasn't yet decided who will start on Friday, but both Tannehill and Matt Moore are sure to see action.
Last week, Tannehill completed 67 percent of his passes for 167 yards and a touchdown. He looked extremely comfortable in the offense, something that should only get better with time.
If Tannehill repeats his performance this week, Philbin is going to have a hard time choosing Moore as the starter.
Russell Wilson is going to see the field against the Denver Broncos after completing 12-of-16 passes for 124 yards, a touchdown and an interception against the Tennessee Titans last week.
ESPN reports that Matt Flynn will get his second consecutive start, but head coach Pete Carroll insists that there is still an open quarterback competition.
It wouldn't make much sense for the Seahawks to pay the amount of money they did for Flynn then not have him start the season opener, but they may have no choice if Wilson continues to get better this preseason.
Wilson also led the team in rushing against the Titans, scampering three times for 59 yards and a score. Despite his lack of size, Wilson has shown that he can effectively run an offense, so we'll likely see another solid outing.
