I like Boozer as a person, dude was super funny and he was geeked when I called out 'HOLDAT' to him one time as the Lakers took the court out of the tunnel. But...
He was pretty much a parody of his old self last year. And the thing is, there isn't much room in the league for 4/5 hybrids like there used to be especially when they aren't good defenders. Boozer wasn't a dude who could guard out on the perimeter especially beyond the arc like modern 4s or shoot threes, but he also wasn't a rim protector or a shot blocker like modern 5s. Combine that with his age and he's pretty much a relic at this point.
And by the way, Stoudemire doesn't even get off the bench anymore so this is probably his last deal as well.
