From what I gather, this isn't anything really significant, but it does tell us that he is still considering the NFL. I kind of expect him to stay in college another year, but this is a good sign. At least he is taking the steps to go to the NFL. It might not be anything huge, but it is notable nonetheless.
On a separate note, I wanted to say that I have become less and less impressed with Robert Griffin III the more that I watch him. I don't see him making NFL throws. He may have a big arm, but he doesn't have a very accurate arm. A running quarterback can only do so much when he is inaccurate. The fact that he can run so fast makes him an exciting prospect, but not one that I want the Dolphins to get.
I am not quite positive yet, but I think that I have Kellen Moore ranked above Griffin III. I need to watch more film on Moore to be sure, but I get the feeling that he is a better passer than Griffin.
That's all I've got for today. Let me know your thoughts.
