I would remind them that they are good. They can still function at a high level, and the season can still be salvaged so long as there are goals still available to them. The goals still available start with winning today, finishing strong, winning the ACC Tournament and making the NCAA Tournament. All that could happen, but so could the reverse. A traumatized Maryland may not win again this season.
Seasons fall apart sometimes.
For a brighter prognosis, I turned to Steve Danish, a professor of psychology at Virginia Commonwealth University in Richmond. But he wasn't rosy. He said the Maryland players were like survivors of a natural disaster. I'm sure after that game they were wondering what happened. It would be like a flood or tornado coming through.
