As a Vikings supporter I think Cousins is a legit candidate for the most overpaid QB in recent times. Deshaun Watson will probably take the gong in the end but Cousins problem is that he is a non completer. Not a choker, that is too harsh. And his stats are not bad at first glance but he just failed to deliver too many times when he just needed to get the job done. And he had quality WR and RB, and for much of his time at the Vikings, a reasonable offensive line. He has the ability to do anything Mahomes or Allen can do. He just does not do it when he needs to. Better to have a rubbish QB and know that you need to replace him than to die (or almost die) the death of a thousand cuts with Cousins.
Probably a reasonable chance he gets injured this season again and Penix gets a go.
