I've seen this movie way too many times...i call it the Benoit Pouliot syndrome...you shouldn't need someone to tell you to ''up your consistency'' when you're in the NHL.
For sure Slaf is a unicorn, and he's just starting his career....you dream of having a player with his size and talent on your team.
But it's definitely a red flag that he can't turn it on more often, especially when you have Suzuki-Cole on your line showing you how it should be done
Regardless....i'm sure he'll only get better as he matures...and becomes a true professional
