In my opinion a 3rd tier QB is just good enough to play in the NFL but must have a decent level supporting cast. Bortles, Andy Dalton, Winston, Prescott, Mariotta
A tier two is a guy who can get you some wins in the regular season and has potential to go on a playoff run but needs a stellar supporting cast and some luck. Matt Ryan, Russell Wilson, Philip Rivers, Mat Stafford, Jared Goff, Alex Smith, Kirk Cousins
A tier one is a guy who is elite and can carry a team and makes big plays in big moments. He has a SB ring and defense fear him. Brady , Rodgers, Brees Rothlisberger
Dak is a tier 3 with limited potential to be tier two. I have to ask if this oline and running game make Dak look like an NFL QB then imagine how good Dallas would be if they had a tier two guy like Philip Rivers or Kirk Cousins.
