Re: Kyle Larson and an apparently sponsorless #5 car... I think it's bunk.
I expect to see at Daytona:
#9 - Napa
#24 - Axalta
#48 - Ally
#5 - Valvoline
I reckon that Rick Hendrick is a clever bean, and that he's probably using the fog of war to either attract some other sponsor with the enticement that they can have a whole car, or that he's using the fog of war as a way of quietly concealing the fact that he's already tied everything up; so that maximum hype is maintained when the #5 is finally revealed on race weekend.
Dare I suggest that this is even more massive and that Hendrick might have attracted a proper works deal with Chevrolet?
