Should Cup Series Drivers Be Limited In NASCAR Nationwide Series?

As the races go by, full-time Cup Series drivers continue to dominate in the NASCAR Nationwide Series. How has the Nationwide regulars done so far this year? Lets look at the stats by best finish by a Nationwide Series regular (or by a driver that takes points for the series).

Best Finish By a Nationwide Series Regular of 2011:
Daytona: Landon Cassill - 3rd (takes points for the series)
Phoenix: Reed Sorenson - 5th
Las Vegas: Justin Allgaier - 2nd
Bristol: Elliott Sadler - 4th
Auto Club Speedway: Ricky Stenhouse Jr. - 4th
Texas: Elliott Sadler - 5th
Talladega: Joe Nemechek - 3rd (takes points for the series)
Nashville: Ricky Stenhouse Jr. - 5th
Richmond: Justin Allgaier - 3rd
Darlington: Elliott Sadler - 3rd
Dover: Reed Sorenson - 3rd

Now let's look at laps led by Nationwide Series regulars:
Daytona: (Trevor Bayne - 9, Danica Patrick 1, Mike Wallace - 1)
Phoenix: none
Las Vegas: none
Bristol: (Ricky Stenhouse Jr. - 28)
Auto Club Speedway: (Ricky Stenhouse Jr. - 10, Aric Almirola - 2, Charles Lewandowski - 2, Kevin Lepage - 1)
Texas: (Michael Annett - 8, Ricky Stenhouse Jr - 6, Brian Scott - 2
Talladega: (Trevor Bayne - 23, Elliott Sadler - 8, Reed Sorenson - 6, Ricky Stenhouse Jr. - 6, Mike Wallace - 6, Joe Nemechek - 4, Aric Almorola - 2, Sam Hornish Jr. - 2, Kenny Wallace - 2, Derrike Cope - 1, Robert Richardson Jr. - 1)
Nashville: (Josh Wise - 5, Aric Almirola - 1, Trevor Bayne - 1)
Richmond: (Aric Almirola - 7, Ricky Stenhouse Jr. - 2)
Darlington: (Elliott Sadler - 23, Justin Allgaier - 13)
Dover: (Ricky Stenhouse Jr. - 33, Josh Wise - 5, Scott Wimmer - 2)

Total: 214 of 2126 Laps

Looking at those stats for laps led, only one race has a Nationwide regular led the most in a race, that was Trevor Bayne at Talladega.

All the races in the Nationwide Series have been won by a Cup Series Regular, with Kyle Busch having the most (5), Carl Edwards (3), and Denny Hamlin, Mark Martin, and Tony Stewart (each with 1). In 2010, we had only one Nationwide Series regular in Victory Lane (Justin Allgaier at Bristol in the Spring), that was the last time we had a series regular win in this series.

So when should Cup drivers not be in a Nationwide Race? I think NASCAR should let Cup drivers be in the Nationwide Series for a maximum of 5 to 10 races, with some weekends with just Nationwide regulars driving. It can give potential for some drivers to show their experience and talent on the track. Drivers that have been in the Cup Series for 5 years or more should get no more than 5 races.

I know sponsorship will always be an issue, but some drivers like Ricky Stenhouse Jr., Reed Sorenson, and many others need to have races with no Cup regular in the field. I'm not saying banish Cup guys from this series, I just want them to be on a limited schedule because I think they should focus on the Cup Championship more.

With just 3 Cup drivers entered in the Nationwide race at Iowa this weekend, can we see a Nationwide regular pull off a win, or will Edwards, Brad Keselowski, or McDowell continue the Cup-Regular winning dominance?
