I merely said that in my opinion the rules should be looked at, so that the rider with the next highest rider is considered over a rider who has just been signed. If the unfortunate circumstances prevail that a second string or reserve is the only option available then yes.
Do you think when one of your opposition heat leaders is unavailable for a league meeting, for circumstances outside the rule book that you should be allowed to replace him with a rider of a similar average? instead of having to use an unattached rider from the league below? that to weakens the field and becomes a lesser spectacle.
