As of today, I would think the defense looks like this for now (and think that 2 d-men are needed):
Robak/? - Petrovic
Racine - ?
Taker - Weegar
extra: McFadden
Thats assume Robak clears waivers or someone else would need to be found to replace him. Defense is gonna need work no matter who's playing in goal if you ask me.
On forwards, I would think that there's a lot of talent there but definitely could use a veteran leader. I do like the forward group though with the talent involved: Shore, Howden, Trocheck, Grimaldi, Butler, Brickley, Wilson, Shaw, McFarland, Martindale, Hodges & Crabb are all signed and probably expected in SA to start the season. Definitely could use another forward as you said, especially if guys like Trocheck or Shore get called up. Not gonna attempt to create lines with those guys but should provide some interesting games I would think (I see plenty of truculence in that group of guys).
