I've always rather liked Budinger, even if he's a marginal player. I agree with chilidawg, though, I don't think he'd get minutes ahead of Turner, Crowder, Smart, etc.
And anyway, we already have two similarly talented 6'7ish wings sitting on the bench not getting any time.
If the Celts would consider bringing in a marginal vet like Budinger instead of getting Young or Hunter a shot, they should probably just cut Young and Hunter right now, 'cause they've got no chance of developing here.
