Stills, Carro, Landry and Parker are the least of my concerns. As long as those four stay healthy the receiving corp will be fine. I am interested to see if Miami keeps five or six receivers? Is Grant a near lock as a bottom depth guy and special teams weapon? How is Hazel looking? And is there some players on other rosters that might be released that Miami might at as the fifth receiver and bump Grant to the sixth spot? For example if Carolina releases Keyarris Garrett (6'3 215 with decent speed) I wouldn't mind adding him as a player on the roster to develop.
I am thinking 5 WRs right now, with Grant as that 5th guy over Whalen and Hazel. Maybe keeping a guy like Rashan Scott on the PS.
Really the number 5 guy will be whoever performs the best on returns. We are all assuming Grant, but he is not Darren Sproles. Sproles was small but Sproles was thick, Grant is tiny . . . Just really worry about him at this level . . . Certainly justifiable. As many times as he makes people miss, it only takes one solid square on hit to end it for a guy that small.
Right now I have:
Qb - 3
Rb - 4
Wr - 5
Te - 3
Ol - 9
DL - 10
LB - 7
CB - 5
S - 4
