Did anyone think about TK's retainer that he requires? Both in Nascar and Indy Car all drivers sign a contract that pays them a salary for there services. The rumor on the street is, he's asking 3+ mil. Between the owners and drivers, they get a big chuck of the sponsorship (partner) money. Even the special treatment (rooms, dining, transportation etc.) that the team supplies for the sponsor at the track comes out of that money. Yep the sponsor paid for his own way. So it stands to reason, that whoever gets TK is going to have to have deep pockets. Indy Car teams can't get that much money to support the whole team and driver.
Racing today mimics the ball sports and we all know what it takes to keep players. Most (not all) race team owners do not own a fleet of dealerships or manufacturing business to support their lifestyles. Their business is owning a race team, and they get a paycheck too.
Here's idea. Ask TK to offer his services to a team for what a sprint car driver gets. 40-50 percent of the earnings the car makes that day! Back in my day we started sprint cars with oxen and got paid with beaver pelts.
