Mathews, Marner, and Nylander have been great but a big difference between us and them are non first round picks Connor Brown and Zach Hyman really contributing. Brown is gonna score 20, Hyman 10. Carrier/Bailey/Baptiste/Fasching have 13 total as a group. They also added Zaitsev who's played really well.
or... they role 3 lines of offense...
JVR-Bozak-Marner.... is their 3rd line. Ours is Carrier-Rodrigues-Gionta.
Hyman (who is 3 years older, but comparable to Fasching IMO), is playing on a line with Matthews and Nylander. Fasching, when he gets a chance, is playing with Nic Deslauriers.
Hyman and Brown get to play with top line talent... our 2nd tier of young players get to play with Brian Gionta, Marcus Foligno, Nic Deslauriers, Zemgus Girgensons, Matt Moulson, etc...
Babcock is playing his Girgensons and Faschings and Carriers.... with his Eichel, ROR, Reinhart spine. And he's playing offense. And wowzers... his non-1st round skill players are producing when paired with his scoring veterans and elite youth...
The biggest difference between Buffalo and Toronto is Who is coaching, and What they are coaching. No amount of stat sheet comparing will change that.
