I believe the reason he isn't included is that he is an atypical, run first QB in the modern, pass first game. Passing is the one component of his game I hope he can focus on and improve significantly in 2018, and hopefully his rehab isn't putting a crimp in that. He can clearly run the RPO game, and create significant problems for opposing D's that are strong against a pass first offense. But until Ground Canada can become Ground and Air Canada in equal measures, the pundits will likely view him as a one trick pony.
That was my first thought, but the list include's Navy's Malcolm Perry. He threw 2 passes last year and one was intercepted.
