yes, but no points for them, none at all. if they want the practice, they can race with them. with no points less sprint cup drivers will race in the busch (or whatever its called now) which gives more busch drivers a chance to compete. and a busch driver will win the championship instead of a sprint cup driver. a busch driver that finishes 25th in a season with sprint cup drivers, will now finish 10th, and he has more chances to get a good solid sponsor, and possibly a sprint cup ride. if he joins the sprint cup at the beginning of the new season, he can still practice in the lower series every week for no points. when if a busch driver joins the sprint cup in the middle of the season, he will be able to compete for points in both series.
