I feel he isn't as good as many believe, but still probably top 10. He has been blessed with playmakers most of his career and if you follow, when some go down with injury, he loses his effectiveness.
He also has failed in most big games.
Yet, top 10 or maybe even top 5 QBs are hard to come by and he came up for renewal at a good time. That is the way of pro sports so good for him on getting the money. It will hurt their cap space some I would guess.
remember when Luck took all that money and they had nothing left to pay other players. If that happens to Ryan and they don't hit on low cost draft picks, we could see a fall off on production.
