Best course of action for Leskinen right now is a year in Laval. Let him learn the NA game, get used to the physicality, get used to the travel, the systems, the culture, absorb every ounce of hockey knowledge Bouchard will teach him and learn what it takes to be a pro on and off the ice.
There is a whole lot of suck and sacrifice to being a professional athlete, but the pay off is immense and life changing.
When I hear things like him dominating at the AHL level for an extended period, great training / eating habits, consummate pro, fantastic teammate with a commitment to winning and a great attitude, then I'll entertain the possibility if him cracking the 6-7 spot, even for a "look see".
Guys coming out of junior / Europe really don't grasp how much of the process they can control on the ice, in the dressing room and off the ice. Bouchard, if anything, will show him just that and we'll see what he does with it.
