It is my opinion that teams with too many staff members and drivers, up yo the current maxima, can gsin themselves quite an advantage over teams with only one or two of each staff members ( CD/TD/DR's). There can also be a major advantage if a manager has many drivers trained to differing abilities.
Considerint this, my current bright spark is to, give us a selectable league rule that only allows a team to own a maximum of 2 each of TD's, CD's and DR's and 2 drivers per car. Or the selection will be to keep current staff numbers maxima.
