Some teams have cap space right now and can make a trade. Having cap space doesn't mean a team will make a trade though. In fact the biggest indicator of a teams willingness to make a trade is expectations. There are few teams with that right combination of cap space and high expectations that have voids that need to be filled...possibly by Calgary who is definitely considered a seller right now.
Washington- Some forecasts call for the caps to be the cup winners this year in addition to the best team in the league. Those are some mighty high expectations! With over 5 million in cap space They have some notable players becoming free agents after this year, namely Semin, Knuble and Poti. Their top six forwards are pretty good but rumours around Semin and Fleischmann continue to swirl, One is injury prone yet skilled beyond belief and one is good on paper but a healthy scratch in the playoffs. Calgary could definitely help Washington's defence, the shut down side of it anyway with Regehr or Sarich. Calgary is looking to shed salary so taking a player going into his UFA year is always a good bet, they play hard and if they don't you just let them walk, Fleischmann might be a fit for Calgary.
Buffalo- The Sabres management and the Flames Management get along really well. Buffalo could also use a bolster on their blueline, Myers is going to be a Norris winner one day but the next best guy might be Jordan Leopold. I know from experience that is not saying much. Buffalo has something Calgary wants too, Derek Roy. Roy is Buffalo's best all around player, very consistent and plays a style that all teams love. If Calgary offered to put Regehr in front of Miller it might be tough for Buffalo to not take. They would need something else back from the Flames in terms of a forward so take your pick out of any one of our centers outside of Backlund!
Columbus- The Blue Jackets have around 6 million in space and need to win to keep the locals coming to the rink. Given the fact that Filitov has not had a good experience there and the Flames would give them a top six forward and a top tier D-man and also possibly a top prospect, say Nemisz it seems a good fit. Filitov is highly coveted in that organization though so it would be a long shot. Worth making a call on though since he only costs just over 2 million a season.
Anaheim- Tons of cap space, more than they need and yet this team is shallow on depth. They have an amazing top line but the player that makes sense is Bobby Ryan. How could they give up on Ryan though? It would be hard but Anaheim is suffering after losing Neidamayer on it's d and needs a puck mover. This may sting to some but White would be an awesome fit in Anaheim, Ryan would fit right in behind Iginla on the Flames Depth chart, a big hole that missing right now. Ryan is worth a lot and the Flames have depth players aplenty, pick a 20 goal scorer, any 20 goal scorer outside of Bourque, in fact pick two. They have the money for it.
Anyway just some food for thought.
