That’s about all the Mavs can do at this point: “The Mavericks have concerns beyond Howard’s physical status, but his injuries are near the top. How concerned are they? ‘Very,’ Mavericks coach Rick Carlisle said Monday. ‘I’m always concerned. It’s been a problem since the third week of the season. We always hold our breath, cross our fingers.’ For what it’s worth, Howard’s newly injured right ankle doesn’t hurt quite as much as his left. However, he still can’t cut very well and is cautious on the court. Caution has no place in the playoffs. ‘It’s something I’ve been dealing with all season,’ Howard said. ‘I just have to get through it like I’ve been and do what I can do to help my team win.’”
