I think it all comes down to sponsorship dollars. I heard a comment on the radio today about the Roush cars at Vegas. Two rookies without a sponsor for that race but Carl's car is fully funded. If they removed Edwards for half the season would they have the sponsorship on that car still filled out?

i think it would be simple to say cup guys cant race for the championship in nationwide but at the same time i think the rules are fine how they are im one of those fence voters

If there was a limit to the number of races a Cup guy could run in the Nationwide series I would be all for it.  Like a 10 race maximum or something.  It's supposed to be a series for grooming the next gen of Cup drivers, but I think the sponsorship dollars have the final say sadly.  You don't see a Major Leaguer playing Triple A ball in his down time unless he's coming back from injury or just not playing well.
