To speak on behalf of most of the people in support of bringing AI in.
We don't see this move as hurting our long-term growth or stunting the development of our young players at all. It is not that we are impatient and can't accept rebuilding, but that we realize we don't have our own first round pick this year and bringing a guy like AI can improve our short term while doing nothing to hurt us long-term.
The guy is not a cancer. He just believes that he is still good enough to be a starter in this league and he is correct. For a lot of teams, he wouldn't be a good fit because he is most effective when asked to be the leading scorer or the go to guy. On our team, he would fit in perfectly because that is what we need right now. We could instantly plug him into our starting lineup and feature him as our main weapon. AI is still capable of scoring 25 ppg in our system and more importantly, he would make us more competitive this season. Do I believe AI is a good fit for us long-term? Hell no. But why not make our team better this season and more attractive to the 2010 free agent class?
Some of you say that bringing in AI will only bring malcontent to the locker room. I say NOT bringing in AI can do worse damage. I've seen every game so far this season and have been there for a bunch of them. After losing some heart breakers, this team has lost a lot of confidence. They need something good to happen before they quit altogether and stop caring about winning (hasn't fully happened yet but you can already see some signs of it). I don't care what you say, it is never a good thing to win less than 20 games, especially when you don't have your own pick. When you lose that many games, which is where we are heading right now, it can have a negative effect on your young guys and it can certainly give free agents a bad vibe about your franchise.
Walsh has said repeatedly he wants this team to be competitive this year and will do whatever he can to do that without compromising his 2010 cap space. If he doesn't sign AI, he will be going against his own words.
