I think he wants to move Hathaway up b/c Flyers don't go to the net and set screens for dirty goals.
Couts did so and that resulted in two PP goals.
But they rarely have a man in front of the net 5x5, which means lots of easy saves.
Hathaway has speed and size, concrete hands but he's not afraid to mix it up in front of the net.
The real problem is the forward group is undersized:
Couts, Foerster, Hathaway and Tippett are the only full sized forwards.
Foerster has potential in that role, but is inexperienced.
Tippett plays "small," relies on his speed and shot and doesn't use his body on a regular basis.
Couts has always been more of a finesse guy on offense.
Deslauriers has the size and grit for the role, but he's a liability in any other role, so if you dress him, it should primarily be for O-zone faceoffs where he goes to the net.
Gauither has the size for that role, but I think he'll end up similar to Tippett, a big shooting forward who doesn't spend a lot of time in the dirty areas. You only need one "Tippett."
