Russell Wilson is one of the most durable QBs in NFL history. He's missed 4 of a possible 220 games
Winston might be a better quarterback right now than Wilson. The Giants don't think so. Most teams don't. We'll see. I doubt it, too, but the combination of effectiveness and injury are likely to cause Jameis to have to start a game or two along the way.
Yeah, I think the crux here is we have different opinions on how good Winston is. I'd probably rank him around QB45 or so and consider him a middling backup.
I don't think Wilson is some amazing QB anymore, but I struggle to see what Winston does better. Wilson has a better deep ball, makes better decisions, and is more accurate. They both take too many sacks. Maybe Wilson gets hurt I guess, but I'd put the odds at Wilson getting benched for Winston as extremely unlikely.
