I think he can handle the AHL, and I think to grow his heavy game (outside of fighting) he's going to have to get used to playing opponents his own size or bigger.
It's nice to think the OHL would help his offensive game, but he also is going to produce points in a different way than he would in the pro game, so I think there may be more value in bringing him to Laval, grooming his game to fit the middle six, and having him focus on puck skills and shooting (which his brother needs to do as well) in the off-season.
