Going to help make some people feel better. These are the teams who actually have a 2015 1st rounder left, and who I think can and will trade their 2015 1st round picks:
Anaheim
Tampa Bay
These are the teams I think *could*, but have lots of reasons not to:
Chicago (terrible cap situation, will use their pick to ease out of that long term)
Detroit (old core, is going to draft with that pick)
This team *could*, but traditionally has not done it:
Montreal
There's just not an abundance of buyers in a position to toss 1st rounders around here at the deadline. So no matter what you think of the price tags based on the last few trades, you need enough buyers to pay the prices, or else the prices come down.
I maintain that many (most) of the assets that are going to be moved around in the coming weeks, will go for 2nd rounders + prospects. I think in a few cases 2016 1sts, could come into play, but most selling teams want something more immediate to satisfy unhappy fans and sell tickets.
