Let's make it even more fun. Which former All-Star and current player would represent the most depressing acquisition?
I think for me it's Joe Johnson. It just works on so many levels...he's overpaid, likely to evaporate completely as a player...and we would end up having traded him away once just as he was getting good, only to re-acquire him as he began to suck again. The clincher would be sending back enough talent to ruin the BKN picks we own.
If we'd drafted well over the past 3 years and actually had a core in place, Joe Johnson would be the perfect guy to help take us to that next step, imo, but that's not where we are at the moment. Ugh. How is he 'likely to evaporate completely as a player?' He's a sf now, yes, but his offensive versatility, quick hands, great passing ability, and superb handle means that his game, much like Pierce's, will age very well, and perhaps even better than Paul's, quite honestly. Plus, his contract would come off the books after this year, anyway, giving us more flexibility, so it could have been a win-win, and I think it would have been cool to see him finish his career in the city that should have been his home over the past 14 seasons.
Now, having said all of that, if we're looking for a washed-up star, Carlos Boozer certainly fits the criteria, imo, lol

. The guy is still a free agent in August, haha

. Wow.
