With Antron starting up his own team and the new rumor of Hagan joining up with Leah and Tony that leaves only Capps at DSR maybe DSR is slowly beginning to transition from a race team and more into a parts/chassis supplier. Capps and NAPA seem like a pretty tight and solid partnership so if DSR were to close down the on-track portion of the organization I'm sure he would not have too much of a problem finding a home or starting his own deal. While not knowing any financials or other stuff from a business perspective I would take a guess the parts/chassis supplier side of DSR is more than sustainable and financially fulfilling especially factoring in the potential elimination of the massive overhead that comes with actively racing week in and out. Its no secret that Don has been looking at retirement for the last few years and maybe with the teams disbanding this is a way out while still being involved in some way. Of course all speculation on my end.
As far as Stewart part of me wonders if Leah brings along her factory stock team maybe Tony might run another car in that series. Its a small schedule which would leave him more than enough time for his other ventures plus he has made hits in that electric cobra jet recently, again another thought that has been floating around in my mind.
