I believe this season hinges on the O-Line. Kyler Murray's success hinges on this O-Line's ability to protect him. He had the best Oline in college which gave him tons of time to scan the field and throw to his weapons. He wont have that on this team. He will be running for his life but KM has shown he has superior pocket presence and ability to scramble when needed compared to Rosen. I really hope this Oline doesnt hurt his confidence.
