I don't know unless there has been some discussion about the Jets being open to trading down and so the 49er's don't want somebody to give the Jets a godfather offer to get Fields or Lance, who they're really after?
You're right it doesn't make a lot of sense, but I just can't make sense of the move at all. Who do they see as being worth two first round draft picks compared to what would be available at number 12??? Seems crazy to me.
