From Larry Lage of the Associated Press:
Person familiar with talks tells AP Cavs have discussed parameters of a possible deal with Izzo
I suppose this isn't really too surprising since the Cavs aren't just going to send a random offer Izzo's way, but it does confirm that Izzo is taking a serious look at this opportunity. He still may very well turn it down when all is said and done, but there is no doubt he is entertaining the possibility of leaving for Cleveland.
