Hard to do considering the CBA is up in the air, but as far as brief thought prior to being able to put the pieces of the puzzle together...
Walk - Bruno, Morrison, Mayers (even though he was good - being scratched in the playoffs burned that bridge), Oduya, OD, and Lepisto. So out of last offseason moves, only two stick - Monty (who was extended prior to season's beginning and Carbomb.
Ship Frolik for a pick this upcoming draft; someone will want him since he earns less than his hit. I'm not sold on Saad being ready. He wasn't completely out of place in the playoffs like he was in the first couple games of the season, but he didn't stick out at all. He turns 20 in October so he ought to be eligible to play in Rockford.
As for UFAs:
With Parise and Suter being long shots, have a conversation with 'em (probably brief). They'll end up getting bucks elsewhere, but it'd be stupid not to have a chat with them.
With Kane moving to C (why not Sharp?), bring in Doan to replace him as a RW or put him with Toews. Character, leadership, decent size. Hope that Coyotes are moving on elsewhere otherwise he'll stay a Coyote. This is probably a bit of a long shot, too, considering he'll take a chunk of the money needed to fill out an entire roster.
I'm not considering Gaustad or Stoll since these guys will make too much money and/or be put in positions where they won't succeed. Neither are 2Cs; however, they may be paid as such depending on how the rest of these playoffs go.
How about Jackman? He's not huge, but plays with some meanness and can be depended upon to clear a crease occasionally. Not quite the PMD this organization always seems to have hard-ons for, though. Carle might be that mobility guy. Still would have trouble clearing the crease with him, though. These guys will also find a place that will give them a raise from their mid 3ish hit, so that might not work. I would not object to a Bryan Allen signing, also.
I may get flamed for it, but I'd consider Rolston on an inexpensive deal. Even though he's old, he most certainly will be taking a huge pay cut and still has a heavy as shit shot. He can replace Keith on a left PP point and probably get a ton more shots through.
Tending will stay the same, most likely.
