Where is his 1st rounder picking? I have not been in a dynasty league for a few years, but I remember teams going from crap to near top with just 1 early round pick (Getting Luck-RG3-Richardson from this year's group).
I only like deal 1 though. Deal 2 is ok, but a 2nd rounder might be pick 12+ (depending on your # of teams), which is really hard to find a good player. Also, Im not sold on LaFell. Deal 3, felix jones is useless, he's a backup, so no way i do that deal at all.
The one thing, VJax and Gonzo are GREAT plays for this year, so if this guy is going for the win this year, i'd offer, VJax + Gonzo for 1st - DeSean - VD. I'd still prefer a high 1st rounder back.
If he's not budging, find another team close to winning this year (preferably struggling at TE) and offer up Gonzo. If i am close to winning, Gonzo would be EXTREMELY tempting if I am weak at TE.
