A few more updates after camp conclusion from Pete and Cable's interviews.
RB: Pete's very excited about RB competition, particularly Prosise who they love as a receiver as well as a back. Prosise and Brooks overlap a bit while Collins is still looking like a first down back. They've already thought about how to expand Prosise's role as a third down back before they drafted him and they can line him up as a receiver or in the backfield. The goal will be to start at 3rd down back and then figure out how to expand it as he gets comfortable.
DT: Expecting huge (starter) contributions from Reed. Great leadership. They'll wait until training camp to figure out who will be 3T and who will be 1T as Rubin and Reed can do both.
Center: Joey Hunt can contribute early because of how smart he is. Size doesn't help him but he's managed it and they'll see, Pete thinks he'll be fine. Britt's move to center is about flexibility and getting more information. They almost did it last year and Britt was working on it mentally before training camp last year but they opted not to go that way. He's looked very comfortable so far. If he can play every position he'll be extremely valuable because he knows the most and has the best communication with Cable. Per Cable, Lewis is the key and has proven what he can do.
Other O-Line: Huge emphasis on flexibility. They like to play rookies from spread offenses at guard at first and then make the decision later about whether to keep them at guard or move to tackle. Liked how Webb finished at RT last season, and Ifedi's flexibility lets them put him at RG. Glow is moving to LG because they think he can handle it, they've always wanted to play Gilliam at LT so this is their chance to do so and he has first shot at it. Gilliam only needs confidence. Sokoli has to develop, tremendous ability and will still play guard and center but is transitioning from other side so it will take longer. Sowell has played every position (including long snapper) and is there for versatility. Odhiambo impressed Cable with his football smarts and Cable thinks he'll be able to play a few spots well.
TE: Vannett is a great receiver and combo blocker. Hard to tell about him coming off the football and blocking DE's single. He didn't have to do that much at Ohio State and so they'll see but he'll mainly be playing at Y spot with Graham/Willson in TE2/receiver spots.
Lawler: Great catcher but too thin, lost 15 lbs since combine. They can get him stronger and his hands won't change.
