Interesting. I don't mind a coach that wants to test put a lineup for a couple of minutes. If it looks shoddy early, bring in yemi. And you keep he and maymon out of quick fouls.
Unless they are using it almost like a protective helmet to prevent another shot on the knee. Though a brace crushing down on a bone bruise would hurt as well.
Just for reference, he could brace up a torn ligament and finish the year without further damage and get it fixed after the season. If he were to play on a sprain, he would be risking a complete year requiring surgery.
