Well look, no one makes it to the NHL by being beer league equivalent. But Callahan wasn't a guy you looked at and proclaimecd, "There's a package that's going to score at a 30 goal pace for a couple of years in the NHL."
And even the 50 goals he scored in the OHL was his overage season as a 20/21 year old playing against, in some cases, kids who were 16.
Prior to that his OHL goal totals were strangely closer to what he'd do in the NHL, which is kind of illustrates just how remarkable his journey was.
