Drivers (or crew chief in the case of Chad Knaus and Drew Blickensderfer) have appeared as rotating guest analysts for the Xfinity, Truck and/or the ARCA Menards Series broadcasts, and usually the same drivers return each year on top of a few that are added into the rotation each year.
The new guest analysts in 2021 were Blickensderfer, Trevor Bayne, Greg Biffle, Chase Briscoe, Matt DiBenedetto, Brandon Jones, Andy Lally, Tyler Reddick, Tony Stewart, Kevin Swindell, and Daniel Suárez.
Guest analysts that returned in 2021 from 2020 were Aric Almirola, Ryan Blaney, Kurt Busch, Matt Crafton, Austin Dillon, Joey Logano, and Bubba Wallace.
Kyle Busch was the only driver to appear as a guest analyst on a 2020 broadcast that did not return for any races in 2021.
In 2021, Kevin Harvick, Ryan Blaney and Joey Logano were in the booth, Christopher Bell and Erik Jones were the pit reporters, and Brad Keselowski, Knaus, and Ricky Stenhouse Jr. were in the Charlotte studio.
