Hahaha... you're doing it again. I didn't say that, because Bayless thinks he good, he's therefore no good. I said that, just because Bayless thinks he's good, doesn't make him more than what he is - a third-string PG.
Good players are supposed to hype their teammates. KG did it with Darius Miles and Bill Walker last year, Lester this year... just like Roy is doing with Bayless. It's just talk.
No, I would not trade Baby straight up for Bayless. Davis has had many very solid games and has been a part of the rotation for a year+ before he hurt his hand. Bayless is only getting burn now because the Blazers barely have five bodies to put on the court at a time. Davis is clearly a better player now, and I'm not convinced that Bayless's potential is higher than Davis's either.
