Editor's note: NASCAR on NBC broadcasters will offer opinions on upcoming races the remainder of the season. This week, analyst Dale Jarrett discusses Sunday's Cheez-It 355 at Watkins Glen, which airs on USA at 2:30 p.m. ET. Note this is a different channel as the Rio Olympics are on NBCSN.
For drivers without a win chasing a championship berth, Watkins Glen could be a game-changer.
The fast road-course race is the most challenging of the five remaining before the Chase for the Sprint Cup field is set. That could lead to interesting challenges for those drivers on the bubble this weekend.
