There's really no signs that we WILL do anything, so I don't know why you'd be disappointed.
We've traded Rondo, we've traded Green, we've traded Nelson, we've traded Brandon wright. Everything we've done this year was set up for us to maximize cap space this summer and acquire draft picks. It's a team very much set up to tank again. We might have won a few games in spite of this, but this isn't a team at all set up to win.
The only trades that make sense is moving Bass, Thornton or Prince (if anyone wants to give up a 2nd). The idea that we are in "buyer mode" is silly. Sure, if someone elite like Dragic can be had for pennies on the dollar, Ainge will kick the tires... but if you're expecting some splashy move to happen that improves the team immediately, you are very likely going to be bummed out when the deadline comes and goes without any action... and we buy out the vets soon after.
