I like the rectified trade better... I do not see the need to trade 4 young players (I count all draft picks as young players) for one big man. Vanek is a big boy, and I do like what you are doing with your team (and we talked in depth about my opinion on Plecs... Not worth 5M, in my opinion), but giving up that extra pick would have been overkill.
I would have approved the deal anyway, as both teams like what they are getting (which, to me, is the most important aspect of my job as a trade commissioner), but the new deal looks a lot better for both teams.
