That is an assumption, that could easily be wrong. Like most, I assume he will say something...but this would be really far from the first time he went on that show and everyone thought he was going to say something big, just to not. Also, at most, I am guessing all he can really do is say he wants to play for them. There is probably more layers to complete in this trade.
'The Decision' wasn't just announcing it himself. Dude got a full set, announced it well in advance, put it on ESPN, and had a really creepy/cringe interview before even announcing it. The comparison is like comparing a gourmet steak and lobster dinner to a lunchables.
