The best sports organizations make tough, unpopular decisions all of the time.
Obviously, the decisions don't always work out, but a fear of failure can't ever be part of the decision-making process.
It's time for Cuban to make another tough decision.
The trade deadline is rapidly approaching, and Cuban and the Mavs must decide whether to be buyers or sellers.
Frankly, the answer is obvious. It has been since the Mavs went 2-13 from Dec. 12-Jan. 9, dropping their record to 13-23 after a loss to the Los Angeles Clippers.
The best thing the Mavs can do is make a trade, if there's one available, that improves them long term. If they must part with quality players and people such as Vince Carter and Shawn Marion, then so be it.
