Adding another 33 year old, rapidly declining player in Craig Smith is the last thing this team needs. Especially considering his $3.1M cap hit will make the salary cap juggle particularly binding in any situation in which Backstrom and one of Oshie or Wilson are in the line-up at the same time.
This is without Craig Smith, and with the extra goalies, NAK, LuJo, and Snively all waived/sent down, and with Alexeyev and Wilson still on LTIR - and the team is still $1.523M over the salary cap running a 22-man roster.
If they need another forward, they have plenty of spare parts that need a longer look already. No need to dumpster dive for a $3.1M, declining player. Bump Protas up. Call up a kid and give him a real role. Give Snively another shot.
