Listed as a groin injury, not hernia. Typically a hernia is listed as such, since it's a protrusion of an organ through the abdominal wall. It was Draper that had a sports hernia (2010).
(I knew a guy so fat, he had a hernia and didn't even realize it, lol.)
Brooks Laich had tightness in the muscle after surgery and never made a full recovery. Basically skated like Abby after the surgery, traded to Toronto as a salary dump (2nd rd pick included). Made way for Ovy to be Captain.
It's just presumptuous to say he had surgery, so he has to be ready to play the season. I'm almost certain he'll start the season on LTIR (10 games and 24 days), or otherwise Brise would have made a deal by now. I can't say how he's going to resolve his cap issue, because I agree sitting Stamkos out for 2/3 of a season is a bit much.
If Cernak and Cirelli agree to $2.25M bridge contracts, Stmakos would only have to sit out half the season, and that would be workable. Then they can deal with Seattle, that actually needs guys like TJ, Killorn, etc. I've looked at the mock draft, and not many scorers are available.
