My real question is: Did the 49ers make that offer to the Jets first?
The only reason that trade would have made sense for the Jets is if they are all in on Watson and they want to maintain flexibility in future drafts. But that wouldn't happen now, it would happen closer to draft day once we get more news on Watson.
If Watson is completely removed from the situation, I wouldn't do this deal if I were the Jets. 49ers should be a good team, and those should be late picks. 12 is a pretty big drop, and the only other addition in 2021 is a 3rd-round pick Granted, not everyone in the NFC West can be good, so maybe those picks will be OK.
We have an extra pick next year already. What we really need is a quarterback. Any trade involving the #2 pick should give us a pathway to improve at QB.
