NFL Week 14 Predictions: Underdogs on Verge of Pulling Off Massive Upsets

Three teams are headed for victory despite being at least a touchdown underdog. The week of the upset is at hand just in time to shake up the playoff picture.

Buffalo Bills over San Diego Chargers

Line: Chargers -7 

The Chargers' 38-14 win over the Jaguars was an illusion of their return to competence. They will be knocked back down this week as they host the Bills.

San Diego snapped a six-game losing streak against the Jaguars, and they did it in impressive fashion. However, that was more due to the matchup than it was to the Chargers turning things around.

The Jaguars can't move the ball, Blaine Gabbert continued to be awful, and the team was in disarray after the sudden dismissal of coach Jack Del Rio.

The Chargers are still who we've learned them to be this season—a mistake prone team with a soft defense.

The Bills enter this game having lost five straight. However, they have looked better the past two weeks, and their offense is springing back to life. They put up a combined 41 points against the Jets and Titans, both of whom have stronger defenses than the Bolts.

Ranking 27th in yards allowed per pass attempt, the Chargers are struggling against the pass. This will make it easy for the Bills to get in their favored spread sets and put some points on the board.

The Bills won't have to rely solely on their passing game either. CJ Spiller finally showed some signs that he can hack it in the NFL last week. He put up a career-high total of 101 yards from scrimmage last week—83 of which came on the ground at 5.9 yards per carry average.

Spiller will better those numbers against a Chargers' defense that is 26th in the league in rushing yards allowed.

It is not their offense that will seal this game for the Bills though. Victory will come because they'll win the turnover battle. The Chargers are 29th in interceptions thrown while Buffalo is sixth in interceptions forced.

Rivers will throw a couple of costly picks, and it will result in a San Diego loss.

Prediction: Bills 27, Chargers 20

Kansas City Chiefs over New York Jets

Line: Jets -9

The Chiefs will win their second straight game due to another dominant defensive effort.

Kansas City and their anemic offense was able to beat the Bears last week because they held the Bears to just 181 total yards.

That defensive effort came on the heels of a game where they held the Steelers to just 13 points.

They will have similar defensive results against New York. The Jets put up 34 points last week, but that was due to being opportunistic, not offensive prowess. New York mustered just 266 yards of total offense in that game.

The Chiefs will be able to force the Jets out of their comfort zone. The Chiefs are seventh in the league in stopping opponents from running for first downs with two yards or less on third and fourth downs.

This will force the Jets to throw to move the sticks, and the Chiefs have been playing excellent pass defense lately. Over their last three games they are allowing just 6.0 yards per pass. That number would rank them third in the NFL for the season.

This will help get Jets offense off of the field quickly and easily. That will allow the Chiefs to play the field position game, which is the only game their offense can handle.

Kansas City will be able to sit back and wait for Mark Sanchez to add to his total of 11 interceptions, and that is something the Chiefs are well equipped to do. They lead the league in opponents' percentage of passes thrown for interceptions.

This is going to be a painful and embarrassing loss for the Jets.

Prediction: Chiefs 13, Jets 10

Minnesota Vikings over Detroit Lions

Line: Lions -8

The Lions self destruction tour will keep on rolling. Detroit has lost three in a row and five of their last seven because they can't get out of their own way.

They are making costly turnovers and incredibly stupid penalties. Over their last three games the Lions have committed 30 penalties. That leads the league over that stretch by a wide margin.

Detroit is facing a Vikings team that is playing better than their four straight losses suggests. Over that span Minnesota's offense has sprung to life as Christian Ponder gets more accustomed to the pro game.

They have tallied 73 combined points over their last three games, and they will be going to work on a Lions team that has allowed 93 points over that same span.

The Vikings have struggled all year in pass defense, and this will certainly be problematic in this one as the pass is the Lions bread and butter on offense. However, the Lions passing game has been inconsistent while QB Matt Stafford plays through a fractured finger.

Over their last three games the Lions have thrown an interception on 4.8 percent of their pass attempts. That would be the second worst percentage in the league if it was for the full season.

This is going to be a high-scoring and close game. And in a close game, it would be foolish to count on the Lions not doing something that will destroy their chances of victory.

Prediction: Vikings 31, Lions 27
