I can't see OKC wanting Kapono. They have plenty of wiggle room financially the next couple years and I doubt they'd sacrifice that for a shooter off the bench.
Honestly, I feel bad for the team and for Kapono. The guy's an excellent shooter when he's got a hot hand and you can tell he wants to produce more to justify what he's getting paid, but he just doesn't have the game. He'd fit as a great role player on any team if he were making half of what he makes.
