They do have NHL experience going for them. I really don't think that Leaf management wants to have their "star" youth playing this season, hence all the off season signings and the PTO's. If the boys on the PTO's and our prospects have equally impressive training camps, I would expect that the PTO's make the team this season. I expect that we will see the first real flood of prospects really getting a shot at making the NHL full time in the 2016-2017 season.
