Jim Nil? Guy fixed Dallas center problem in 12 months and has people excited about the team again while still working on a tight budget. Ray Shero would be a nice choice also at least being him in as an assistant the guy has tons of experience and isn't afraid to trade players.
So far, he has made some good moves, but I don't know if what he did is going to work or not. Last season, they finished 8th in the conference and got bounced in the first round. If Dallas can put something together this year, then I will agree.
Oh, and Dallas is going to spend to the cap limit. They aren't on a tight budget or anything because they aren't spending much.
