I'm thinking we get an extra pick at the end of round 3 for Wallace and an extra pick at the end of round 5 for Lewis (the comp picks were officially announced in mid-March last year, so official word may be coming soon...not sure if that determination gets pushed back a bit since the draft is now in May, though). I know that compensatory selections are not tradeable, but having those extra comps in our pocket might make it more likely that we'd be willing to part with our regular picks to move up for someone we really might want.
We don't have the ammunition to move up into the top 10 unless we are willing to part with our second round pick, and I'm not going there. Let's say that somehow Evans makes it past Buffalo and Detroit (perhaps the Bills opt for Ebron over Evans with their pick, waiting to take a wideout later because it is a deep WR class, and then Detroit goes for either Gilbert or Dennard at CB since they signed Golden Tate and re-signed Brandon Pettigrew).
What if Tennessee opts for Taylor Lewan at #11, because they just released their long-time RT David Stewart and their long-time LT Michael Roos is entering his 10th season? The Giants, who need OL help more than anything, would then likely be willing to trade down, since the big 3 OL would then be off the board (they could go for Notre Dame's Zack Martin, but he could be had a bit later, so a trade down could work with them, especially since we have a history of trading up with them in the past).
Such a trade would be important now to get ahead of the Rams (I assume they'll take one of the tackles, Robinson or Matthews with their earlier first round pick), and if Evans fell into their laps at #13, they would pounce on the opportunity to add a big target to team up with mighty mite Tavon Austin.
The last time we traded up with the Giants, we moved from 32 to 25 to get Santonio and it cost our 3rd and 4th. Would you be willing to move up from 15 to 12 for our 4th and 5th? Assuming the earlier comp pick projection holds true, that would still leave up with 6 draft picks, which is about right since we already used our 2014 3rd rounder on Shamarko Thomas. We'd have Evans at 12, then our regular 2nd rounder, a comp at the end of rounds 3 and 5, and then our regular 6th and 7th rounders.
