If Marko Jaric added 10 points, 5 rebounds, 5 assists and say 1 steal per game, he'd be quite valuable. He's capable of doing that, but he's too inconsistent on too regular a basis.
Mark Blount could certainly manage 10 points, say 7 rebounds and a block a game, but again, never seems to be able to do it consistently.
Eddie Griffin could also add 10 points, 5 boards and 2 blocks per game. Again, lacks consistency.
I'd expect Troy Hudson could put up 10 points, 5 assists and a steal per game. Somehow doesn't manage to.
If all those guys played to their potential, Kevin Garnett, with his expected 23, 13 and 5 averages, would have a decent 4 guys to run with. Mike James could slot in as the starting point, and he's capable of 20 points and 5 assists per.
Simply put, if all these guys played to their potential, the Wolves wouldn't be great, but they'd at least make the playoffs.
