Rasho and Nazr can both suck...but Rasho hardly ever sucks defensively, even when's forced to defend the basket against guys like Kobe or Dwayne Wade...Rasho is exceptional at doing this, and he is a disruptive force to any teams interior game. He can shoot if he wants to, but defensively he keeps people out of the paint effectively.
Nazr is...well it's just about which Nazr going to show up. If Nazr is on his game(holding on to the ball), rebounding well, and not blowing his defensive assignment, the Mavericks get routed. Nazr can look awful..but he can also make a teams interior defense look like paper mache.
They both have something to offer, situationally if nothing else.
I get nervous because we have the weakest/oldest/least athletic part of our team, going up against the strongest, youngest, most athletic parts of the Mavs team...
How long is our 60 year old swing rotation of offensive players going to be effective having to run all over the court to doubleteam, rebound and defend?
Experience is fantastic...but at some point youth will be served.
