How does Trackhouse handle this logjam? [Of having four drivers under contract and only two charters]
Chastain is under a multi-year contract and producing quality results; he’s not going anywhere. Neither, likely, is Suárez, who is finalizing an extension, according to sources briefed on the matter.
…
This leaves finding spots for [Zane] Smith and [Shane] van Gisbergen. Trackhouse, though, may not be permitted to own four charters. Under the proposed terms of the charter agreement teams are negotiating with NASCAR, there is a provision included that would limit teams to owning three charters, according to team sources briefed on the matter. (Joe Gibbs Racing and Hendrick Motorsports would be grandfathered in.)
This means that even if Trackhouse buys a third charter as expected, it would still be one team short, and one of Smith and van Gisbergen must be slotted elsewhere.
