Just because you limit the number of cars on teams doesn't mean those sponsorship dollars spent on the eliminated teams would go elsewhere in NHRA. The sponsors buy in to what the teams have to offer, their ROI and activation potential. Those bigger teams have in house PR powerhouses that are able to do things with hospitality, press releases and other media that smaller teams have a hard time competing with as well. Helps make things look awfully attractive to potential sponsors, especially when money is so tight everywhere. Dunn and Grime Boss has been a prime example of activation and the way a company can really grow their name and sales through sponsorship, and with an independent team no less. But so has Traxxas with Force...
And think about this 2 team rule you're talking about. Split up DSR.. Okay, so now Don owns two cars, Tony owns two cars, his Daughter owns two cars, Johnny Gray owns two cars.. Everybody "buys" their parts from DSR, leases rigs and hospitality, crew chiefs and crews become employees of the respective owners, but still share info. DSR becomes a manufacturer and consulting firm for Top Fuel racing as well as fielding their two teams. But only for those specific umbrella teams and anybody else who ponies up enough cash.
What have you changed other than titles of ownership?
You never go to a race to lose, but there are realities of budget limitations. People pick and choose their battles, which is why you run 10 races trying to be competitive rather than all 24 trying to conserve every part. The Dote family car will be just fine. Everybody has their struggles. Racing is about persevering and finding what it takes to be competitive. When you don't have a million to spend on Alan Johnson consulting on your tune up, the struggles are just more apparent.
