QB needy teams are desperate. Desperate teams tend to make bad decisions.
it's the compound decisions as well.
Panthers just signed Thielen. This is a direct effect from the trade, he is now their #1 WR. Three year deal. Fair guess is that it's probably a two year deal, and they will eat dead cap in three years. But hey, they traded DJ Moore the same year the best free agent WR was Jakobi Meyers, so you get what you get.
So, now they are paying 30-something WR a bit more than they want to (I wager) , as they rebuild, because they need
someone catching balls. They are pretty much locked into improving their team through free agency for the next few years, they would need some historic Day 3 picks over the next two years otherwise. Their picks will probably all make the team however, because they are inexpensive bodies.
