From a source who PM'd me and who will remain anonymous, but who I have some level of confidence is telling it like it is:
It is my understanding that the Draft Advisory Committee papers must be submitted by the university on behalf of the athlete.
It is also my understanding that Darius Marshall submitted his papers to Marshall, that [one of the coaches] said he would send in the papers, and that Darius never received his grade from the Advisory Committee.
I don't want to get into a pissing match with others on the board, but this is what happened.
Thank you, Anonymous, for the clarification.
I have to agree with guru, still, though... it's just not that hard to find projections on where one should be drafted... how accurate any of them are is its own question, of course, and it remains a possibility that Darius read some things that led him to a more positive conclusion.
Again, though, as said in the other thread... I just think this is an unnecessary situation to begin with... expand the NFL draft if you have to, but don't take away a player's eligibility until he actually gets drafted and signs a contract.
