Other QBs do not see progression in him and he's been playing 4 years. I suspect thIs is as good as he will get.
Cousins is much better. Take away 3 of Winstons starting receivers and put him behind a tissue paper front line and he's nowhere near as productive as Cousins.
So who gets the blame for the Vikings being shit this year? Their absolutely garbage offensive line, their coach, or their GM?
