listen man...Dont backtrack.
You said people who dont believe in him are suckers, but yet the only things you have to say about him being any better is that he can improve on his faults. Ok, i agree on that. he can improve.
We are saying it as of what we see right now!
not just that, if every prospect improved on his faults we would have a crazy amount of world beaters, the P4P debate would include more than a handful of people. (or primarily 2).
The fact is, You say when people are saying fact about his style right now its "speculation". The only speculation here is that he can improve. It will or wont happen. THAT is speculation.
