I think we're seeing his breakout season. He has a champion team-mate and two talented drivers with winning pedigrees in Bowman and Larson. HMS as a whole looks formidable again, which is a joy to see. He's had enough time to get to grips with the Cup cars and the level of competition, and he has a crew chief whom he is familiar with. I think Byron has sucessfully evaded the clutches of "bust" status.
I’ll copy and paste from the race thread....William Byron is having a hell of a season this far, while some are wondering when the 18, 4 or 11 will win again the 24 is cranking out good to great finishes each week. Stealthy. I think he may win another race or two before the playoffs start.
