How Ricky Stenhouse Jr. and Austin Dillon can clinch at Homestead

They're being overshadowed by the bigger and closer battle for the Sprint Cup title, but the championships will be decided in the Nationwide and Camping World Truck Series as well this weekend.

It's the first time since 2008 that champions in all three series will be determined on the final weekend, even though the Cup Series title race is much closer than the other two championship battles. (Of course, the new NASCAR rule that requires drivers to declare a series championship to run for has helped significantly.)

Because of Elliott Sadler's crash at Phoenix, Ricky Stenhouse Jr. holds a seemingly insurmountable 41-point lead over Sadler. Why? Well, two weeks ago at Texas, seven cars parked within the first 15 laps. So Stenhouse would have to crash or have something go horribly wrong very early in the race. Possible? Yes. Probable? No way. Stenhouse just needs to finish 37th.

In the Truck Series, Austin Dillon has a 20-point lead over Johnny Sauter and is 28 points ahead of James Buescher. Dillon needs a 17th-place finish to guarantee himself the championship. It's quite remarkable that Buescher is mathematically alive for the title given that he failed to qualify at Phoenix in the second race of the season.

So, who you got on Friday and Saturday? Will Stenhouse and Dillon clinch or will Sadler, Sauter or Buescher become champions?
