LaMichael James is a superstar returner, Perrish Cox can return, and AJ Jenkins is capable as well. With that being the case, why should Ginn make the ream? He's a pure special teams player at this point, while the others can play offense.
Ly own prediction is that Ginn is cut AMD LaMichael James is the 6th WR/4th RB. James, Williams, and Jenkins all fight for playing time, with Jenkins and Williams alternating as an active top 46 player. This is all assuming Moss makes the team.
