Very cheap for the 1.02. You should be able to get a 2/3 como, rather than late 3/early 4+.
A 2 and a 3 along with a future first would be tough. I think the pick 38 and a future first could move him into the 2nd if he wanted
In most of my drafts, the guy moving a top 3 pick gets a 2/3. I don't think I have seen a top 3 pick moved for this little, myself. Not that it doesn't happen, just hasn't in my drafts.
The late 3/4 range isn't enough for me to pass up one of the top 2 guys, hopefully Calvin. In that range you're picking between, for the most part, unproven potential, older production, or risk/limited upside. Is Ridley/V.Jackson/random 1st enough for Calvin or Green? Or Tavon/Murray 1st? In my opinion, no.
Trading for a 2/3, there is at least hope for an elite (or near elite) player still in his prime. Graham, Harvin, Gronk, Marshall, et cetera.
