You don't think clearing your nasal passages would help you to breathe easier? Do we just have noses to smell?
Of course it helps breathe, people don't get their septums operated for no reason... On the other hand, do you really think he breathes with his mouth closed when he skates all out and goes on a breakaway? You really think that's what kept him to 3 points in some 20 games at the end of last season?
Please. Anyone can do sports by breathing through their mouth.
I like what I see from this season, and if he keeps it up I'll be a huge fan, but to use this nose nonsense to excuse his poor up and down performance so far in the NHL (before this year) is not realistic.
He has (had) an ego problem, as shown when he decided to play in Ste-Adele instead of the AHL, and has shown a poor work ethic until last year.
If he matured and got better over this summer, then great. I'll be the first one to admit I was a wreck at 23.
