The NASCAR Xfinity Series has seen multiple drivers split seat time in a car, and even chase the owner’s championship.  Normally it’s done with a rotation of Monster Energy Cup Series drivers and a veteran crew chief.  JR Motorsports is choosing a different path for the drivers of the No. 8.  While they have used a couple of Cup drivers like Chase Elliott and Ryan Preece, most of the schedule is covered by developing drivers like Jeb Burton, Ryan Truex, and Zane Smith, in the car for the Camping World 300 at Chicagoland Speedway on Saturday.
