I agree that Brockers and a #10 is too much to move up 3 spots, but if the Bears included their second (#40), it would start to make sense. Even their #3, I might listen to.
I do find it believable that they're shopping Brockers -- if he's asking to negotiate a long-term contract now. He still has 2 years left on this contract! This year at 3M, next year at 6.1M. There is no reason for the Rams to renegotiate now.
Brockers had a good rookie season but he's been pretty quiet since. He's a capable starter, but it's a position that could be upgraded, even with a cheaper guy. Decent run-stuffers with minimal pass rush can even be found in the second round or later for under 1M.
A #14 pick could've been in a Pro Bowl already - Bockers has been good but he hasn't really lived up to the draft slot and his contract. Aaron Donald and Robert Quinn were #13 and #14 picks. And we passed up Pro Bowler Dontari Poe at #6 to trade down for Brockers and Pead.
If Brockers is asking is asking to renegotiate a deal that already averages 4M annually for the next 2 years -- you know he's asking for more than that, probably a lot more. If they're looking to move him, it's probably way too much for his production, so they're trying to move him now to avoid a big problem with him just ahead. I just wish they wouldn't have traded Langford if they're going to move Brockers. It does create another hole.
