I hear ya.....I think of it as more a special size of player. Not to compare him to another great....but Slaf's body type and size is like a giant Crosby.That sounds great and It might be but it's also a huuuuuuge red flags.
How many player in that league have that weight and are very good?
One and it's Ovechkin
That's a whole lot of weight to carry around, trying to be explosive and gain some speed (cause skating never been his strongest attribute)
200lbs on a 5'11 guy would be a lot of weight as well. Add 4 inches to Crosby while maintaining the same proportions would probably bring him up close to 40 more pounds.
Slaf is a physical specimen and if he can maintain/gain explosiveness and speed.....look out!
