It's completely Jake Locker's starting job to lose, but crazier quarterback switches have happened in the past. The fact is that Locker has to start all over with a new coaching staff, and that won't be an easy task.
Jason La Canfora of CBS Sports sees Zach Mettenberger likely jumping ahead of Locker on the depth chart before the preseason even concludes.
You can't discount the fact that Locker wasn't brought in by this current coaching staff, so there aren't any ties here. If Whisenhunt really likes what he sees out of Mettenberer, then he could easily choose to dive right in with Mettenberger.
However, Locker's issues have mainly been health-related. He's shown glimpses of being that quarterback who can win games and be effective. If the same quarterback who played so well in the first four weeks of last season shows up in training camp, then he'll win the starting job for Week 1.
Whisenhunt was displaying a lot of faith in Locker prior to the draft, and even Titans CEO Tommy Smith said that Locker was the starter, according to John Breech from CBSSports.com.
Those feelings still have to mean something even with the drafting of Mettenberger. The Titans were going to draft a quarterback all along with this new staff.
Mettenberger will have to have a flawless training camp to win this job before the first regular-season game against the Kansas City Chiefs. No way the Titans throw a project quarterback into the fire at Arrowhead Stadium against a formidable Chiefs defense.
The only way this could happen is if Locker just looks that bad in preseason. My educated guess is that Locker holds his own in training camp to silence the rumors pretty fast on his starting job being in jeopardy before Week 1.
However, if Locker can retain his starter status for the entire season is a whole other issue. This will be a hard camp battle to ignore, but Locker is a good enough practice player to win this job pretty early.
