well, it seems that ainge is being a good GM in that he is "interested" in any nba player who is 7 foot tall and not dead. i think "interested" here means danny would take a look.
however, to believe, based upon the quote above, that ainge is actively and seriously going to sign any of these guys is another matter all together.
i think for mutumbo, ainge decided to not offer a deal since mutumbo is viewed as offering less than powe and BBD offer. that is, he would not have really added anything to the celtics. i am guessing, but i believe this since if ainge thought mutumbo would help the celtics he would have made an offer.
ainge is the same guy to try to get karl malone out of retirement. and did get PJ brown out of retirement.
who ainge eventually adds will be interesting. but i think they will have to clearly have more to offer than who is in the second unit now.
