I think Johnson will get 7 and 8 but I think it will take in the ball park of 4-6 years to get those 2. He is so good but the competition from JGR is catching up. I think Harvick at SHR will be a big threat as well and believe it or not, I think Jr will be a title threat here soon. He was actually very good in the chase. Chicago killed him from the start but he climbed back. I'm not sold on next year for him but I think the year after he will be his best year to date.
I see Harvick, Kenseth, Kyle Busch, Keslowski, Jr, Kahne and Stewart all being legitimate threats as title winners for the next few years along with Johnson. Hamlin and Edwards have the ability to claw in there as well.
