The only worry is that MLSE does the same thing with him that they did with Matthews: roll out the red carpet and turn him into a 'celebrity first, hockey player second' by inserting ego into his head by featuring him in hundreds of promotional videos that have nothing to do with hockey and by spoiling him at every turn before he even plays his first game.
Unlike they did with Matthews, they have to keep him humble and make him work for his rewards, not simply reward him before he ever sets foot on the ice. Don't fill his head with ego and make him some kind of fashion celebrity movie star. Keep him focused on hockey and not create any kind of impression that he's this party dude who likes to hang with celebrities after the game and go to concerts and put on outrageous costumes. I never saw Crosby, Ovechkin, Gretzky etc as those types of guys even though I'm sure there's footage of that kind of stuff out there but it's never been their main identity like it has been with several of these Leaf players the last 10 years. We get it players are humans too and want to have fun outside of the game but it seemed like the non-hockey promo material they showed us about some of our players were just juvenile and far outweighed the amount of material containing them actually involved in the game.
Let's see if they learn from these past mistakes or if they're just going to do it all over again.
