Just re-watched the first half, looking just at the bigs. I've got notes. If there's interest, I'll post them up. Meanwhile, I'll sum up the half. I'll post again after I finish the second half.
Bonner was great on defense, though the Spurs doubled his man virtually every time he got the ball. Sadly necessary because he got scored on when they didn't. He's played out of his mind and has managed not to be a liability. It sucks when that's the ceiling for your center. The reason we laugh at the comparison to Horry is that Horry managed to be a difference maker, and could make a play when you needed it. You also didn't need to double team the Darrell Arthurs of the world every single time they got the ball against Horry. But Bonner made smart rotations, switched well, was tough, made the smart play EVERY time and got some strong rebounds because he was playing strong and paying attention at all times. Zero lapses that I could see.
