I guess I'm more familiar with knee injuries in terms of NFL players and fantasy football, but it seems way to early for Stoll to be getting back on the mat at the beginning of the season. He had an ACL tear and MCL sprain, mid March right? I believe it was operated on shortly after Big Tens. It's good that he's confident and champing at the bit, but that seems risky to me.
Look at Jamaal Charles in the NFL, he tore his ACL in October 2015 and still isn't seeing playing time. If a smallish NFL running back needs almost a full 12 months to rehab, I can't imagine a big dude like Sam would be able to go that much sooner. Add the weird ways knees can get torked in wrestling and I'm nervous.
It's possible the injury is less severe than I thought it was, but for my money, keep him out until it really matters. I'd be happy to see him work and rehab until 2017 and then begin wrestling into form with Big Ten and NCAA tournament peak in sight. I guess we'll have to defer to Tom's judgment on this, but the last thing we need is a re-injury due to rushing back too soon.
