In our league we forgot to uncheck the promotion block and now half of us are pro and half are rookie. How can we get the guys that are pro back down to rookie.
There's no nice way, the league system is intended to be a competitive ranking system. It's up to hosts to disable promotion/relegation if they don't want it active on their league.
If you are playing casually though, then you can reset your team to go back to Rookie. However, in the process you will lose all drivers, staff, design progress, facilities etc. Your budget will be reset to 50,000,000 and you will be allowed to keep your XP levels.
