Yeah, my optimism level with the draft has been all over the place today. But I also don't think the Giants take McCarthy, I'm not convinced they'd even want Maye; I think the QB talk is all a ruse to try to get teams to jump them and take all four QBs assuring them either Harrison or Nabors. The Broncos and Raiders would have to give up more than the Vikings, AND they are in the Chargers division, so if the Vikings do trade up to #5, it would almost surely be for much less than the threat of three 1sts. If the Vikings do trade with the Chargers, would they trade Addison and a 1st since the Chargers would likely miss out on the top three receivers?
You have the opposite issue trading with the Falcons and Bears in the NFC, they'd rather the Broncos or Chargers get the QB. The Titans might be the spot to trade up to if the Chargers aren't being reasonable. But heck, I've seen reports that McCarthy might organically land at 11.
So many ways this could go. I just don't want to see the Vikings get conned and out maneuvered.
