The Cup Series veteran took a lighthearted jab at Letart for showing up in a tie.Letarte shared his take on Byron's long-awaited win since Daytona, noting how the #24 team won purely based on tact and fuel mileage. Iowa produced especially poor tire falloff and allowed Byron to extend his final green flag run to 144 laps, a marked increase from the 100-lap fuel window."It's, it's hard to run bad, but it sometimes can be more emotionally draining when you run good and don't win. And I think that's kind of what we had out of the 24 and then here today, I don't think they were the best car. I think Brad was the best car, but I think it didn't matter because the 24 had the best strategy, which was pit well before you could ever think you could make it on fuel and then get enough yellows to make it," Letarte said via his X handle.Dale Earnhardt Jr., meanwhile, paid no heed to his analysis and instead went for a playful jab at his appearance."Weird seeing Steve in a tie," he wrote.Steve Letarte currently works as a color commentator for NBC, TNT, and Prime Video.
