There are other ominous signs for NASCAR

Of the 53 cars trying to make Sunday’s Daytona 500, at least 17 lack full-season sponsorships.
Morgan-McClure Motorsports, which won the Daytona 500 three times between 1991 and 1995, closed its doors recently.
Multicar teams are dominant. Cars fielded by five multicar-team owners won 34 of 36 races and accounting for 81 percent of all of the top-five finishes in 2007.
After boasting that television ratings proved it to be America’s second most successful professional sport behind only pro football, NASCAR now tries to distance itself from numbers that last year showed nearly 1 million fewer viewers, on average, for each of the races in its top series.
