Leaving aside that the Blazers might kidnap Danny Ainge, and the amount of money Aldridge would leave behind in Portland - would you want the Cs to offer him a max deal this summer? (Please do not respond with "THAT WOULD NEVER HAPPEN" and its variants. I understand that this is a very unlikely proposition.)
More generally - do you want the Celtics to offer a max deal to a guy in his late 20s with proven "star" power - or would you rather they held out for the next big thing?
You can answer either the general or the specific question.
