Z would be a great fit for this team, he could give them a inside presents which could get there outside game going + its a big body to play guys like shaq with.
I agree. I also agree with the rest of your post, but I didn't feel it was necessary to quote it all.
The experiment with LaFrentz (big man with outside shot to lure other centres ie. Shaq away from the basket, opening up the lane) has not worked out the way the Mavericks anticipated. Their success has come from the performance of their big three, not a diversionary tactic.
That's not say LaFrentz is totally useless, and it would be better to keep him rather than trade him for someone who won't fill the Mavs' needs. If they do trade for Z, I think they should play him at centre and Nowitzki at power forward (or bring in someone else to play PF, with Dirk at SF), with Bradley coming off the bench. I don't think Z or Bradley could match up against the likes of KG and Duncan at PF.
