I think that PRUITT and WALLACE offer a heckuva lot more than any of FULLER, CUNNINGHAM, and MATTHEWS. As to FULLER particularly, he's shown very little despite having the advantage of having played at TEXAS A & M. He's here to be TANNEHILL's baby rattle...or he better be! CUNNINGHAM is slow as heck, and drops passes. MATTHEWS seems to have the most upside of the 3, but HOGAN is the only one actually making a noise worth noting.
I have my doubts about NANNEE as well. He's been a mediocrity on his best day everywhere that he has played. Am I supposed to believe that he's now magically a #3 or even #4 NFL WR? No sir!!!
SHOW ME!
Preseason games may not be much, but at least they're real games where MIAMI's O and D will be playing against non-teammates w/whom they are not familiar, and w/whose "system" they are also not familiar with. "Practices", of whatever sort, don't yield enough info. So many players are great in practice, but vanish on Sunday, while others look terrible in practice but "bring it" on Sunday. Again, SHOW ME...and do it in actual football games.
