The teams were equal, but loads of [A] didn't turn up, so we had to steal players from [C], which won't happen again.
All the people being/ have been recruited recently for [A] are reserves.
You can count on all the [C] turning up cause they are composed of all the veterans, but [A] people have other things to do and, on the whole, aren't that commited to the battle (no offence intended, just saying what I percieve).
