I think the draft value chart breaks down a bit when we go into the top 5. Trades happen that theoretically shouldn't.
Belichick rarely has an interest in trading future picks.
So, let's start with using our first 3 picks. Theoretically, this gets us up to 4th. The Giants may be willing, or not. They may ask us to add a 2019 pick. Now, I do NOT think the the Giants would do this, However, if they don't want a QB, they might prefer our 3 picks to Chubb or Barklay. So, sure, we might get the deal for #2.
CONCLUSION 1
We can put together a package that moves up to #4 that leaves us with more picks than in 2017. In fact, we'd likely trade down in the second and pick up a 4th and 5th, giving us the full amount of 7 picks with two 2nds instead of a 1st and a 2nd. As was the case last year, we would have already trading picks for players, bring in Shelton, McCourty and Patterson.
So, we hardly rape this year's draft by trading our first 3 picks.
CONCLUSION 2
We can make the deal for 4 with CLE if the Giants chose Chubbs and our QB was available at 4.
CONCLUSION 3
Is Chubbs a top defensive player comparable to McGuinist and Seymour? If so, then Belichick might consider him to be worth the 4th.
CONCLUSION 4
Lesser trades (moving up to 9 - through 22) would not cripple our draft or our team. In any of these cases, we would be using 2 picks to get one player (23 and 31 would get us to 9). Are there players worth it? Most of us would say no. Belichick may agree or disagree. Clearly we would consider must more likely to get a starter at 9 or 15 than a lower position. Yes, Belichick would need to believe that this player is worth 2 players.
Is the best LB or DE in the draft worth a 10 pick? worth both of our firsts? I truly don't know.
Well, first of all, the #2 overall spot is valued at 2600, and - assuming that the Giants don't want a QB for themselves, the #23 (760) + #43 (470) + the Pats 2019 1st (likely to be in the bottom four) isn't going to get that done. Especially since ...
... A) that takes them well out of range for most of the non-QB top prospects in this draft
... B) Buffalo can offer them the #12 (1200) AND #22 (780) in this draft, just to open the bidding.
So, the Pats could expect to offer the #23 (760) AND the #31 (600) AND the #43 (470) AND the #63 (276) AND something else hypothetically worth ~500 points in trade value (like the Pats 2019 1st-rounder) just to get the Giants to listen.
That's a metric butt-load of roster-building opportunities going out the door for just one prospect.
