Matt Duchene has a more chiseled jaw now. Any trace of the baby fat of his rookie season — when he was 18, in 2009 — is gone. His voice is quite a bit deeper. The boy of four years ago now sounds like a man.

A new diet — gluten free, no sugar, no dairy — has him looking leaner. A new workout regimen, mostly the one used by his good friend, Penguins star Sidney Crosby, has produced a more muscular look.

Now we will see whether Duchene's new off-the-ice lifestyle produces a new, improved look on the ice. The Avalanche center is coming off the worst season in his three-year career and is eager to make amends.
