Are the Mavericks buyers or sellers?

ESPN.com's Brian Windhorst sees the Mavericks as buyers as we get closer to the NBA trade deadline.

The Mavericks have been in the market for a home run acquisition for the past two years. Free agency hasn't worked out. They're loaded with expiring contracts, they are totally constructed to be big-game hunters.

Windhorst and others debate just who the buyers and sellers will be this season in today's 5-on-5.
