Doesn’t sound crazy to me. A team would have to let go of 2 firsts on top of giving an astronomical fully guaranteed contract that he is demanding. For a guy that can’t stay healthy and whose PO appearances leave little to be desired.
It's not just that though. Ravens will probably match what any team is offering, so x, y, z team will be doing the negotiations for them (they have their own team to focus on, so why waste their own time?). Also, if they have an offer sheet, that money is locked until the Ravens match(or not) and then intentionally screw themselves over for something they probably won't even get because point 1.
Not to mention the difficulty of the guaranteed money issue, or teams not willing to give up a first this year (but once draft and/or FA is over, there should be interest).
I'm sure many would want Lamar, but the logistics don't make sense for ANY team, no matter what, until after the draft, or at minimum the bulk of FA is over. Doesn't matter if it was the reincarnation of Tom Brady/Peyton Manning in his prime.
