Ehh, Mahomes, Allen are recent examples of teams trading up for a highly picked QB working. Possibly some others but I don't feel like putting my thinking cap on.
Allen is not really equivalent.
Buffalo traded 12th, 53rd and 56th for 7th to draft Allen.
Mahomes is closer but KC was already a MUCH better team than Carolina when the trade was made. 27, 91, and the next years first for 10. Basically they were already a division winner caliber team that wanted to go from having a game manager at QB to a potential game breaker at QB
to get Young the Panthers had to give up 9, 61, a future first, and future second. There's a chance it might not blow up on the Panthers because, well, the NFC South is garbage, but that was a metric asston to give up with a high chance of it blowing up in the Panthers face. I mean Young could pan out to be a worthy #1 pick QB and it would still be a terrible trade that sets the Bears up for years to come just because the team has nobody worth a damn for him to throw it to.
