This honestly seems legitimate. Kevin still has the ability. That is beyond question. 2017 aside, a slightly down year in which SHR's transition from Chevy to Ford was being made, Kevin and Kyle have been the two drivers to watch in the Cup series since 2014. Nevertheless, Kevin is one of the older drivers, and it would not come as a surprise to me if he were to retire within the next two or three seasons.
On the topic of whether or not getting another Cup title helps or blemishes their respective legacies, right now, Kyle Busch is looking to be the juggernaut among them all. He, technically, was this year's champion. He's been in title contention every single year. He already has fifty-plus Cup victories, and who is to say that he might not go on into his forties? He has also been re-writing history books. He has shown he is capable of winning at each and every single track. With some guys, you think "the road courses are going to be his best shot." With others, it's "he can only get a win at a restrictor-plate track." With Kyle, it's "how many wins is he going to get at Kentucky?" "Do you think he might reach Darrell Waltrip's mark of twelve wins at Bristol?" You know he is capable of finding a way to win anywhere; what people look at with him is how far he will go each week. That is what puts him in an elite group.
Kevin is gonna be in a tier slightly below Kyle. He may be the one known for playing mind games and intimidating fellow drivers, but he has also been known to choke a few wins away. Then, you've got his pit crew, who have lended helping hands to a few L's over the last few years. Also, the fact Kyle has already surpassed all of his victory tallies in each series speaks for itself. Kevin's going to go down as a guy right on the same level as Rusty Wallace. Rusty had a dominant period as a driver, but also was left ruing some lost title opportunities.
No matter what happens, though, Jimmie Johnson is definitely going down in history as the best of this era. He is not even done yet! What he and his new crew chief could possibly do with the Camaro in 2019 is going to be of huge interest.
