- Markieff Morris has only appeared in 20 games for the Mavericks this season but the 34-year-old forward plays a key leadership role, Eddie Sefko of Mavs.com notes. Morris says his practice habits are part of the reason why his words and actions carry so much weight. “You can’t just talk it, you got to still be able to walk it,” Morris said. “And that’s what makes these guys believe in what I say. Obviously, I don’t play (in games much). But if you catch me in practice and see me play, you’d say, he really still can bring it. It’s just not my role for this team (to be in the rotation). I think that’s why people believe what I say. I show it in practice all the time.”
