KYLE BUSCH. #4. Kyle Busch was a factor at the front of the field in pretty much every race in the regular season. Ever since he broke his win drought of over a year at Pocono, he has been on a roll. He won two of the last six races of the regular season and didn’t finish lower than 10th place in any of the other four. Let’s not forget that he is, in fact, a former champion of the sport, as he won the title in 2015. That season, he drove in just 25 of the 36 races thanks to injuries he suffered in a nasty wreck at Daytona. However, he turned it on when he needed to in the playoffs to win that title, proving that he knows how to win when it matters most, which he could use to his advantage once again in this season’s playoffs..
