Forget about last season's injuries. Lets pretend all these guys stay healthy...
Peterka is still inexperienced and not physical, Thompson is a low-IQ player still learning a position he transitioned to just two years ago. Tuch is well-rounded but still doesn't play as physically as he could/should.
Benson is still a Bambi, Cozens is still learning and a relatively low IQ player foe a C, Quinn needs to get consistent and stronger, and none of them play a physical game, even though Cozens can after another 10-15 lbs.
That top-six can be fun to watch in the regular season when playing a team that stinks or isn't on their game, on a back-to-back, etc. When playoffs come around they will get routed...out hit, out-worked, out-disciplined.
Last season I thought for just a blip that the league was trending back to an end-to-end skill game. That was wrong. Regardless of what wins games in the regular season, the playoffs require discipline, defensive responsibility, physicality or the ability to withstand a heavy forecheck, with players willing to play straight ahead and work hard around the boards for the puck, going to the net and taking punishment. The Sabres are about 160 degrees away from that type of team, and I don't think KA realizes that or knows how to get the team closer to that style.
