My first question is this, OP: Why did you start a thread asking for opinions if you've already made your mind up and are not going to heed the counsel of others?
Second question: Why are all of your theories based on conjecture?
Blair hasn't struggled to score against anyone because he lives in the paint, grabs offensive rebounds and puts them back up quickly. He's effective against short players, tall players, skinny players, all players. Again, like Manu. Would you ever say to take Manu out of the game? No, even if there's a mismatch, you want what he brings to the table; the creativity, the instincts, the desire, the aggression.
In Bonner's case, you talk about him "stretching the floor" but, like many have already stated, it's untrue. The reason that Bonner is so wide open in the regular season is because his defender sags waaaay off of him. How good is he at stretching the floor if his defender doesn't even follow? I also believe that Bonner has become a much better player over these last two years and that he could be even better this year. However, your argument that he has all the things that Blair has is absolutely false. When you see Blair do something incredible, which is not that unusual, you see the team get hyped up, jumping off of their chairs and hollerin'. When Bonner does something outstanding, which is rare, his teammates clap and say 'good job'. Blair's mojo is infectious, while Bonner just doesn't have it.
Either way, they will both play against the Lakers.
