Kaep is indeed only going to get better, but the division is getting better too. Seahawks are still on the rise. St. Louis probably won't threaten for the division, but are on the come up as well. Arizona is a good QB (hell, Alex could easily end up there next season and make them better) and a coach who can run an offense away from being taken seriously. Not saying that this team right now is our peak, just that nothing is guaranteed after this season.
