I've said this in other threads, but I'll repeat it here.
Hawks were a talented team last year. However, Nashville was able to skate circles around them in the playoffs. Preds would constantly have a dman skate the puck up ice, and still be able to quickly have two men back if needed. Quite simply, Hawks, as talented as they were, needed to get faster and Bowman has addressed that.
Murphy isn't nearly as good as Hammer at closing the gap or shot blocking, but he is faster than Hammer. He's also a righty, which will make for quicker and more accurate outlet passes than Hammer (lefty playing on the right) throwing a backhand pass up ice. Also, Murphy is young and will hopefully improve.
Saad is a faster player than Panarin. Panarin can skate through the neutral ice with ease, however he hardly ever needed to because he'd start the large majority (80%) of his shifts in the offensive zone. Saad is a beast at moving the puck up ice and against tougher opposition. Saad is a better even strength player for us, however we do lose an awful lot on the powerplay (where the big difference in points starts to occur).
Hawks may have lost Hossa, but did bring back Sharpie. Sharp is still a very good skater and will help with this teams speed. Some Stars fans have said his hands have gotten worse, so I don't expect he'll be the same player as he was two years ago, but he can still put up 30-40pts and be a veteran presence.
Hawks also signed Tommy Wingels. Wingels has struggled the last two years, but he's fast, playing for cheap, and is a Chicagoland native.
I also think the young kids from last year will take another step forward. Hartman and Schmaltz were great last season, but struggled playing their first playoff series. That won't be the case this season. I also expect good things from Forsling (21yo defensemen) who played nearly half the season last year and showed high skill in preseason. Hayden and Hinostroza could also be real hidden gems (like solid secondary scorers, not like 30goal guys).
What I'm trying to say is this team got faster. Being faster doesn't necessarily mean we're better (Avs are a fast team and look how good they are), but it's what this team was lacking in that series against the Preds. I'm okay with trying this route.
