Continuing the Favre trade comparison:
Of course for a similar scenario to play out it would mean we don't get Watson or Stafford, and we don't take a QB at 2 - if that's the case it must mean they believe in Darnold, which makes it less likely they would pursue Rodgers if he were put on the block after the draft.
I guess if somehow they didn't love Darnold but still had him rated ahead of this year's prospects, then maybe? It's a pretty narrow window of possibility.
