O'Brien's Warning: Don't Poke the Bear Named McKenna

Former NHLer Shane O'Brien is essentially telling Toronto fans to pump the brakes on whatever they're planning with Gavin McKenna, and when a guy who played the game at the highest level issues that kind of public warning, you should probably listen. O'Brien knows what it takes to survive in this league, and he's clearly seen something in McKenna that suggests the kid can handle himself in ways that go beyond the stat sheet.
