Umm... I am basing that on Griers own words and what he was told by Mac. Now if you want to call Grier a liar, feel free to do so but don't put that on me.

From Will:
I said, the exact quote, "I just want to know what your plans are for the future. Are you going to bring in more guys? Am I a guy you don't see playing here in the future?"
He said, "You're welcome here in the future, you're a Gator, but I'm not telling you my plans. I'm not giving you any guarantees."
Two weeks later, I decided to have one more meeting, man-to-man, and ask McElwain what the future held. I kept asking him what I could do to make it work there. He finally ended up saying, "Maybe a fresh start isn't the worst thing." He said that, and I said, "So I guess that's the move."
I'd say that it's more than just speculation and in fact, Calloway has been much more of a problem that Will ever was or am I missing something?
