I wouldn't be too big of a fan of either of those guys, unless, as you stated, a new contract could be worked out. Davis has pretty much been a disappointment for a guy taken with the #5 pick in 2017. Granted, he hasn't worked with quality QB's, but it isn't like Love is an instant upgrade, that we know of.
Lawson is due to make $15M this year, so yeah, a rework would need to be done. He's had 2 major leg injuries (ACL & Achilles), but at the right price.
Sounds like Davis might be released at some point, but the Jets have until the final cut to do that (to save money), so guessing he is trade bait until then.
