While there are lots of competitions, it seems like things are really pretty straightfoward outside the DL/OLB carousel: K/P/LS -- it's clear who they are. QB -- it's clear who the three are. RB -- there are two vets who were productive last year, two old vets on their last legs, and two rookies. Straightforward competition. TE -- there are two vets who were productive last year, a late-pick rookie, and a UDFA who is impressing in camp. Straightforward competition. OL -- the whole starting OL from the latter part of last season is back, and most of the reserves. There are also are two rookies. Straightforward competition. WR -- all the WRs from the bulk of last season are back, plus one new vet who's an obvious keeper. Straightforward competition. ILB -- all last season's ILBs are back. There's some competition vs. other positions because of ST-heavy roles. Also, there may be some competition with "big nickel" specialist safeties. S -- the top three safeties are back as is the 5th (Brown). 4th safety is up for grabs, as is the possibility of again creating a 5th safety roster slot. CB -- all of last year's CBs are back, plus the guy who was injured all year, plus a keeper rookie. Straightforward competition, except to the extent that CBs and Ss compete with each other for certain reps (on all four downs, actually).
