For me the most interesting battles will be as follows...
RB: I am real curious to see where Ryan Williams ends up after training camp.
OLB: San Acho and ???. Shaughnessy, Alezander, Okafor and Schofield, who wins the job or will we start the best loser?
SILB: How long can Brinkley hold off Minter?
CB: After Peterson, how does the rest of the depth chart shake out? Cason and Powers are battling for the #2 CB spot, but the loser might not fit well as a slot CB. Arenas does fit as a slot CB so can he win the #3 CB job. Also, does Flemming take the next step?
S: Will anyone win a starting spot or, like OLB, will it just be the best of a poor group?
The rest of the roster comes down to production IMO. Palmer is set at QB, can he be productive? Our top 3 WRs are set, can Floyd and Roberts be weapons and take advantage of playing opposite of Fitzgerald? Can any of our TE's be consistently productive in any way? Will the offensive line take a significant step forward? I would argue that the talent is there, but that doesn't always lead to better production.
We will see.
