BTW something that may change the math... if Rice is suspended to start the season. I think they may keep 4 tight ends this year if they like Irv Smith, so that does say probably only 6 receivers, depending on what they do at RB.
The numbers:
Locks:
Worthy, Rice, Hollywood, Watson, Skyy, Toney (to me in that order, although the team probably has Toney ahead of Skyy)
I know some will want to argue about Skyy and Toney being locks but I think Reid has been pretty clear about wanting to continue to develop both of them.
Bubble:
Justyn Ross, Remegio, Powell, Washington.
The rest are camp fodder.
