These are some of the guys that I think we'll look at, however, because there's very limited supplies of players available - especially for a low level, 3rd pairing, hard-hitting, shot blocker, the prices are quite high. All prices are IMO.
Milan Jurcina - UFA - Isles - major hitter, ~100 in 37 games, 65 BS - Cost - 3rd round pick IMO
Steve Staios - UFA - Isles - decent hitter, good shot blocks (37 GP, 36H, 72BS) - Cost - 3rd rounder
Bryan Allen - UFA - Carolina - 50GP, 66 hits, 110 BS - Cost - 2nd rounder
Tim Gleason - price prohibitive + didn't want to play in Canada
Pavel Kubina - UFA - TB - 50 GP, 75 hits, 75 BS - Cost - 2nd rounder
Andy Sutton - UFA - Edmonton - 29 games, 49 hits, 51 BS - Cost - 4th round pick +
Scott Hannan - UFA - 45GP, 34 hits, 79 BS - Cost - 4th round pick
Realistically don't see anyone else worth even mentioning.
