I think the volume of tight ends that are being drafted these days is why he'd leave early. You get drafted and boom you're earning a nice paycheck. Plus, Miami is tight end U. Neanderthal NFL coaches and GMs are going to look at what Graham is doing and will want to get in on the action.
So let me understand this, the volume of TEs drafted are why he would leave early? Can we assume the same volume of TEs will be eligible in the 2014 (leaves early) or 2015 (stays for another year)?
2013 NFL Draft: Of the 16 TEs drafted last year, 10 were drafted after the third round.
2012 NFL Draft: Of the 12 TEs were drafted, 9 were drafted after the third round.
As for TE U, maybe that helps. I think it would help more if he put up 500 receiving yards and 8 TDs along with running a sub 4.65. This guy is not Graham at all. In fact, who in the NFL is Jimmy Graham? 6'7 265 LB TE with a sub 4.6 40 yard dash and a 38.5 Inch Vertical.
