This is good context, thanks for posting. To me it actually shows the price isn’t as bad as I thought. Those moves were moving up 17, 13, and 13 picks. The Pats would only have to move up 10 picks. Yes 15 to 5 is a greater move than 25 to 12 in terms of value, but 15 itself is a much greater value than the starting points of 27, 25, and 27.
Based on those trades a think 15 + 2022 first + one other minor piece could be enough. By minor I basically mean not 46, JCJ, or Gilmore. Maybe 96, maybe a lesser player.
The issue is that those teams likely weren't bidding against other teams who were seriously motivated to move up to those spots. I posted those previous trades to show the bare minimum on a trade up here.
The cost of any particular trade up is:
1) At the threshold that a team is willing to accept to trade out of the spot; AND
2) The highest bid over that threshold.
So even if the Bengals were technically willing to trade 5 for 15, 2022 1st + minor piece, if the Panthers were willing to trade 8 & a 2022 1st, we're not getting the trade up.
I think the actual cost would be closer to 15, 2022nd 1st, a 2nd, a 3rd & a couple young players like JC/Wino.
I think the Goff/Wentz/RG3 trade ups are going to be informative to look at as well in terms of the massive overpaying compared to charts, even though they were for higher picks. Especially Goff/Wentz because I believe the big 4 QBs are all a fair amount higher rated than those 2:
Goff - The Titans traded 1, 113 & 177 for 15, 43, 45, 76 & the Rams' 1st & 3rd the next year.
I kinda think that's the bare minimum it would cost the Pats (2 1sts, 2 2nds, 2 3rds, maybe get back a 4th & 6th).
Wentz - The Browns traded 2 & a 5th the next year (which converted to a comp 4th if the Browns got one) for 8, 77, 100, next year's 1st & a 2nd the year after that.
RGIII - The Rams traded 2 for 6, 39, the Redskins 1st the next year, & their 2nd the year after.
