A few of points about Scal:
He brings 6 fouls to every game. He rarely makes a bad foul, and when a hard foul is called for, the other guy knows he's been fouled.
He is rarely in the wrong place on the floor or in a play. His defensive rotations and help defense are solid.
He hustles. Sometimes its to no avail, but it sets a tone and example for the young guys. He models and mentors. He shows guys how to live clean and work hard in the NBA. He's a good team mate. He is by no means the most talented or athletic, but he gets the most out of what he's got.
Knocks on his weight and conditioning are overstated. I've seen the man close up. He's not jacked, but he's not soft either. Even if he is the worst physical specmein in the NBA (he's not), he's still in the NBA and holding his own. Can't do that if you're not fit.
He has some savvy vet moves. I remember a game against Detroit 2 years ago when he was inbounding and no one could get free. He did a slick bounce out of bounds off his defender and got another chance with a fresh clock.
Maybe he's overpaid. Maybe not. It's not my money, or yours. If Wyc doesn't mind, niether do I.
