I'd like to see Dallas go after the combo of Emeka Okafor and Raymond Felton, two guys that I think have the potential still to become much better than what they've shown and would probably do better as complementary pieces in Dallas instead of building blocks in Charlotte. Dallas is looking to get more athletic and talented, and Charlotte is a miserly operation that would love to dump salary. Okafor still has a ton of money coming to him and Felton is expendable with DJ Augustin in the mix now.
Okafor is not exactly Bill Russell, but he can get you a double-double and defend the post. That's all the Mavs need at the center position. Certainly much better than what they throw out there now. He seems to be past his injury problems.
Felton to me looks like a potential Chauncey Billups in the making. Sometimes it takes guys a while to figure out how to play the PG position. Billups and Devin Harris took awhile to blossom. If Felton can add a reliable 3-pt shot, he instantly goes from mediocre to good. He shoots a terrible % from the floor if memory serves. Bet you he gets better looks alongside Dirk. He's a hard-working high-character guy, and he's a potential successor to Kidd. Maybe he won't ever be an All Star, but I can see him working out for us in a Derek Harper-esque fashion.
The big names come up in trade talks and rumors but there is a use for identifying underutilized talent on other teams and making it fit better for you. We've seen it with Ariza going from a scrub with Orlando to a VERY good complementary piece in Los Angeles. We've seen it with Brandon Bass getting buried on the bench in New Orleans and blossoming with Dallas. A lot of people will say "Okafor and Felton? meh...." but I think that's something the Mavs should look at.
