Last I had heard, they were going Cup racing with Justin Haley in one car, AJ part time in another, and the other full time driver was TBD. Which leads into another point....
As many keep saying, 2022 is probably THE year for teams to try and expand/break into Cup, as the technological playing field will likely be more level than it has been... well, ever. It's going to be pretty ruthless in terms of team success and failure, and I think that a team we see now in 2021 may not exist come 2023/2024, losing to one of these newer teams. It's really kind of a crapshoot. Only teams I think are "safe" are HMS, JGR, Penske, and SHR.
