Hi there and welcome to the Cafe - I always love seeing new faces around here and hope you stick around this great place
As for the deal, I think it's a terrible deal for you. For Peterson, you need to get the king's ransom, and those 3 guys aren't even close IMO. For AD, I think you should be able to get a starting QB better than the Amish Rifle, a top-15/20 RB and a WR with a higher floor than Meachem.
Hass is looking like he could be a viable QB option for those in trouble at the position, and while I think you can/should upgrade at QB, I don't think this is the way to do it. Now, if you get something like Kolb, Blount and Burleson (just spitballing here), then I might change my tune a bit, but I think that's the baseline for deals for AD you even consider ...
Hope this helps, and please do post any updates/further questions
