I think we have to think about grooming Stafford's replacement sooner than later. Nothing against the guy, but he's got a lot of mileage on his arm and a lot of sacks on his body. I just can't see him playing more than 2 more years, and I wouldn't expect that last year to be entirely impressive.
I don't think Wolford is our QB of the future, many think Perkins has starter potential, I don't know enough about him to speculate.
Unless Snead is thinking of going the free agency, steal someone else's starter, route (Kirk Cousins) then next season we should think about adding one of the young former starters who were thrust into a starting job too quickly. (Mitch Trubisky comes to mind. Someone else mentioned Drew Lock.)
