Until they aren't, Campbell (if his knee's ready) & Moses are the starters at LT & RT respectively. Lomu & Crownover are competing for OT3 vs OT4 reps; but if everyone else is healthy &/or not sucking then neither would be forced to play many meaningful snaps. Every other Tackle in camp is competing for Practice Squad space. Regarding any 6-Lineman packages, I suppose I can see that happening, with either of them, as both in-line blockers or as Jumbo FBs; though when considering the effort the team made to sign both a Blocking TE And a Blocking FB, I'm not sure how I would feel seeing them use non-position players in those roles, again... Isn't that how Tonga got injured last year?
