A real coach certainly wouldn't hurt but if needs coaching to find offensive instincts, we are sunk. The wrist may likely never feel 100% again, he has to learn to deal with that.
Take the puck to the net!! Not wrist dependent. Do not pass to a Dman on the rush unless he's in a scoring position. The puck is supposed to be on YOUR stick to make plays! Plaster a guy in the corner to create some space!
None of that is wrist dependent, unless his wrist is between his ears. You think nobody is telling him these things? Not his agent? Not a former coach? Not a parent (if they know)?
