We can argue about who is the best QB for the long term, but it isn't even close who is the better QB for right now.
Exactly. We know Gray is flawed, but his strength running is better than the best Shortell can give us throwing. Max just has not shown he can make enough plays with his arm to make up for his lack of any real running threat. Hopefully he continues to get better, and gets the accuracy to make the simple plays more often. For now Gray is our best chance to win.
