Except all those you mentioned had good measurables outside of maybe Rice and Bruce 40 times, but I understand what you mean.For me its easy to say "take a chance on a guy" but this isnt my job that on the line. if coaches believe they can do one thing and thats COACH. some just might think "you bring the athleticism, height, and good frame/ and or weight and i will have you making plays".BUT cmon guys look at what position we are talking about receiver when there are dudes like Rice, Moss , owens, and bruce some of THE BEST receivers EVER didnt come fromthis position isnt about your measurable AT ALLUM, UF, FSU, UGA, ALA, LSU, OSU, TEX, USC, AUB, CLEM, and much more
Wouldn't say measurables don't matter at all considering the best WR in the NFL, Megatron, AJ Green, Dez Bryant, Julio Jones, Andre Johnson, etc.. all had sick measurables.
EDIT: college players can be good without those great measurables, though
Adding on to this point, Moss was at ND and was kind of sort of FSU for a miniscule period of time. He was a big school guy
