One game doesn't define PB, nor does it do Lin.
His strength and weakness have been beaten to death. There were 4 pages of cursing on that stupid foul alone, at Clutchfans game thread. It was extremely dumb, but it's not what PB is about.
Street ball or not, have you ever seen him back down from anyone? Have you ever seen him NOT working hard?
I don't like him, not at all, simply because I don't like not gifted player, but I do respect a hard worker. You are not going to get flashy super stars in all positions, every team needs some blue collar workers, and a junk yard dog. PB is just that one.
