The other thing that has me tapping the brake a bit with Denver and visions of playoff greatness... the fumbling problem.
They do it too often, rarely (if ever) recover their own fumbles or those forced. They need to get better at not losing the ball and then covering it up when the do lose the ball. That will bite them horribly bad at some point.
There's a lot of good happening with this team, but there's the potential for some ugly if they're not careful. And, if Holliday ever flips the ball again prior to crossing the endzone, they should scissor kick him in the head - that could have been a big mistake.
