With the preseason already halfway completed, NFL teams are beginning to get the framework of who will be starting and sitting come September.
Some position battles have been decided, while other position battles have yet to be won.
The following is an update on these position battles from around the league.
Unless Tebow plays well, this job is Sanchez's to lose, and he certainly won't go down without a fight.
Sanchez looks like a new person this season, as he seems much more confident in himself, his situation and his team.
Advantage: Mark Sanchez
On Monday Night Football, the Patriots decided to sit star quarterback Tom Brady and instead start Ryan Mallett.
This move came as a surprise to many, for it seemed as though Brian Hoyer was a clear favorite to win the backup job.
Mallett was 10-for-20 and even threw a touchdown, while Hoyer went a disappointing 5-for-17.
Advantage: Ryan Mallett
With this position battle, it's very hard to tell who will be named "the guy" when all is said and done.
Cole Beasley, Dwayne Harris and Kevin Ogletree are all making cases to be named the starter. Beasley had the best night of the three against San Diego, coming down with seven catches for 104 yards.
Ogletree added four catches for 60 yards, while Harris, the incumbent, ended the night with four catches, 42 yards and a touchdown. We'll stick with Harris, for now.
Advantage: Dwayne Harris
This position battle has been decided. Ryan Tannehill will be the starting quarterback of the Dolphins (per ESPN and the AP).
Tannehill looks to lead Miami as a rookie quarterback and should be able to get everyone involved on offense.
This quarterback loves throwing the ball short and should rack up completions in 2012.
Winner: Ryan Tannehill
Beating out former Pro Bowler Matt Hasselbeck, Locker now needs to take the reins of a very talented team in Tennessee.
He and Kendall Wright will grow together and should look to be very productive for years to come.
Winner: Jake Locker
Doug Martin benefits from the fact that incumbent LeGarrette Blount has no ties to new head coach Greg Schiano.
Schiano and his staff recently used a first-round pick on Martin and are rooting for the Boise State product to win the job.
It's quite possible that Blount gets a good number of carries, but it's only a matter of time before the Buccaneers go with Doug Martin as their guy.
Advantage: Doug Martin
Kevin Kolb has looked very bad in the preseason, but John Skelton hasn't done anything to win himself the job, either.
At this point, Kolb's salary makes the Cardinals want to give the signal-caller as many chances as possible.
Don't be fooled, though; Kolb's time as the starter is running out.
Advantage: Kevin Kolb, by a hair
