What's the purpose of the coach change reduction, where you can't reuse recruiting efforts a previous coach used?
imo,
1) you receive no recruiting effort from the previous coach and you're on your own with a full budget for the late recruiting cycle. You're kind of facing uphill as you need to unlock all efforts as it is.
or
2) you should get the carryover from the previous coach and cannot duplicate efforts. This doesn't make a lot of sense and seems to tie a new coach into the old coaches recruits.
In my limited situations, there is no way there is near a 1/3 carryover of previous coach effort.
