If your going to pick one driver from ea race .
Then you pick any driver from them races (Cup Drivers too)
But I like what nad.-john. said =
2 cups,1 nns,1 truck
or if there only 2 races that week you pick
3 cups & 1 NNC or Truck
or if there only one race that week you pick 4 drivers from Cup or NNC or Truck what ever race that week
