I am interested to see what happens with Decker. I truly feel that him leaving will affect both the WR depth and Holliday's standing with the team.
There are quite a few WR's who are also good return men in the draft.
Mike Davis at Texas, Odell Beckham Jr at LSU, Bruce Ellington at SC, Josh Huff at UO, Robert Herron at Wyoming, Davante Adams at Fresno St. There are also quite a few RB's who can come in and be a speed back plus a returner.
