Once upon a time we traded 12 and 42 for the 3rd. If I can get that type of value I'm all in. Say 26 and 56 for the 12th.
Chargers and Panthers seem like the biggest threats. Maybe Raiders and Colts.
If we deal 5 and 18 for the 2nd all those other teams would be looking at 1's, 2's, and maybe 3's spread over a couple of years. That is a lot to give up. If I am the Chargers I'd stay pat and settle for Herbert. You have Eason, Love, and Fromm plus some FA QB's. Add in the hip injury and I'm not so sure teams will give up that much draft capitol for Tua.
If we draft Tua at 5, have to IR him for a year, and he turns out to be unable to play.....we can survive that and nobody has to be fired (even if he costs a 5 and 18). If those other teams give up a 1st and a 2nd this year and next (could take more), and Tua never plays a down, I think heads roll.
