I think Briere has a strong opinion about how he wants to build the team.
Seems to want 2 way centers with size (explains no interest in Rossi) who can play in a box and one and be almost like a 3rd D-man. Jett (5'11 200), Berglund, Nesbitt, Gard. Ruohonen (listed at 6'2 205), Only Quinn is undersized (5'11 177) and he might move to wing.
Scoring is more of an emphasis on wing, where the Flyers have a deep group, Zegras, Michkov, Martone, TK, Tippett, Foerster, Brink, Barkey, Bump, Grebenkin. Of this group, only TK and Tippett are older than 25.
One reason is the growing emphasis on attacking with D-men on the cycle, which means you need smart forwards, especially centers, who can cycle back to the blue line and protect against odd man rushes. Which is why I think Briere's big acquisition is going to be an offensive D-man who can move the puck, set up the offense and shoot.
As far as Buium being that guy, 51g 2-6 8 at ES. With 15 hits and -17.
Andrae 39g 1-9 10 at ES. With 44 hits and +12.
And they probably are looking to upgrade over Andrae as the 2LHD.
