Mavs have a leadership problem | Cuban and Harlabob argue on Twitter

This team has not been able to replace all of that yet, and they might never be able to. Since they couldn't interest a Chris Paul or a Kyle Lowry, we might just be stuck waiting for this team to learn all of these things the hard way. If so, I think it's going to take a while.

I think we've discussed most of the culture changing players in this thread besides Butler, so they aren't easy to come by.  You are probably right about our group needing to find their own way.
