Mariota: ESPN QBR season rating of 59.7, good for 9th best. Respectable, but no significant progress from last season. (Last season Mariota had a 59.1) Winston: QBR season rating of 39.4, good for 24th best. That's a very bad QBR, and a significant drop from last season. (Last season Winston had a respectable 59.5) Winston also had a better QBR than Mariota in their rookie season, 57.2 to 48.4 While part of Winston's regression this season can be blamed on having a worse supporting cast, some of it is on him. 39.4 is bad!
