Actually, I think MIA will just replace ONE of our WR's with a Andre Johnson type of starter. And I believe that odd man out will be Turner.
Ginn will become the backup speedster to the #1 WR we aquire and be our starting KR. Hartline will battle it out Camarillo, Turner, and Bess for the remaining 3 WR spots with likely Turner being the odd man out.
With the addition of a playmaking TE and the #1 Andre Johnson type, we wont have such a big need for Turner's big body and Hartline, Camarillo, and Bess will beat him out, JMO.
Of course, should MIA be able to trade Camarillo for a draft pick, then I can see them keep Turner in that scenario..
