I also heard today from a true insider ,one of the gerbils (the most popular one, is likely done with working on Sundays)
NBC's going to need to shake up its booth soon, IMO.
Jeff Burton's been out of the car for a decade and so much has changed since then. His strength comes from having relationships with the drivers, and pre-race would probably suit him best.
Dale Earnhardt, Jr., I could honestly see him stepping away and focusing on the CARS Tour, JR Motorsports, and his other short track projects. But, man, he is the best booth analyst in the sport.
Steve Letarte is another NBC strength.
I like Rick Allen, but I wouldn't complain if NBC called Dave Burns up to the booth. Burns has been fine every time he's done commentary of Xfinity races on NBC/USA and ESPN2 before that.
I also wonder who's going to end up replacing Mike Joy. I personally think Joy could do this another eight years if he wants to, but who knows when he's ready to hang it up. And I would hate to see Mike Joy go through a rapid decline in the booth the way the late, great Ken Squier did in the late-90s, or the way Al Michaels has on NFL.
Conventional wisdom says Adam Alexander would get that job, but Fox is very high on Jamie Little too, so who knows.
I imagine Adam Alexander would be the PxP guy for TNT if they go their own way. But, I imagine Amazon and TNT will both rely heavily on NBC resources and NASCAR Studios.
