Obviously, safety is going to be the biggest battle. I mean, Reid is probably penciled in for now, but I'm 99% sure that we're going to go through the majority of training camp with Dahl/Spillman as the starter. The hope is that Reid is going to win that role. They're not going to GIVE it to him.
The #2 and #3 QB spots will be important. Colt McCoy is probably the front-runner, but they'll go with Tolzien for now, since he knows the system best. I think those two will be fighting it out. I predict they'll try to get B.J. Daniels on the Practice Squad.
Spell RB between Kendall Hunter and LaMichael James will probably be the closest matched battle, but I think that the team will be trying to figure out how to get them both a lot of snaps anyway.
Slot WR will definitely be up for grabs. Manningham, Williams, Jenkins, Patton, and even Lockette will be fighting for it. But to be honest, I think just getting a spot on the team will be a huge victory for whoever gets on as a WR. Our WRs rotatte in and out quite a bit. I have a feeling that this is Kyle Williams' last training camp as a 49er.
#2 TE will be fought by Vance McDonald and Garrett Celek. No idea who wins that one.
The offensive line is pretty much set, but they're going to be fighting for the 6th and 7th lineman in games. Same goes for the defensive line and linebacker positions.
Cornerback will be pretty competitive too. Tarrell Brown and Chris Culliver are the youngest, while Carlos Rogers and Nnamdi Asomugha are the most high-profile ones. They'll be fighting for the top three. I think all four will definitely make the team though. We need depth at the cornerback position. I'm of the opinion that you can never have too many good cornerbacks, especially since this is is a spread-it-out, pass-first league.
