Yeah like some said already it's a very rare draft a QB is considered a guarantee, if there is such a thing really, that it would be cause for concern. And of the two examples, the Bucs tanked for Jameis Winston lol. And the Eagles ended up trading 6th overall to the Dolphins who picked Jaylen Waddle and then subsequently traded back up with Cowboys to ultimately pick Devonta Smith. The Cowboys picked Micah Parsons with that pick... so ultimately the Eagles tanked to pick Devonta Smith when they traded out of two players who are better than him. It's just such an unknown that the success of tanking I'd say isn't worth even doing it let alone altering the draft process to try and avoid it. But like asshole face says it comes down to gambling so it'll probably happen.
