Right now everyone thinks there are a ton of sellers but as we get closer to the deadline I think some of those would be sellers are proven to in fact not be sellers at all. Doesn't mean they'll become buyers but they all wont make all of the moves everyone is speculating over. Just like the Wings won't move all of the players that are being speculated as being available (i.e. Howard, Nyquist, Daley, Jensen, Glendening etc.)
Right now, the only teams I can confidently name as being definite sellers are LA, Ott, Det, and NYR. Then there are the bubble sellers like Chi, Ari, Phi, Florida, NJ, STL. Some of those teams will stand pat, some will sell, and some may even buy (i.e. Phi). Some of those teams still think they have an outside chance of making a run to the wild card (i.e. STL).
So, right now a lot of people think the market is flooded with sellers. I just don't see it that way but time will tell. Either way, it unfolds, there will be a direct impact on acquisition costs.
