Just as an aside, it works a lot better in the Sportsdeck ALeague/EPL comps
There, AE comes only from the same position.
So its not a bad tactic to have a deliberately non-playing keeper that you always start.
Means they are available for VC loops (if they play late enough in the round)
But even without that, it means that your keeper will only sub in as AE if they get a positive score. Its basically insurance against copping a negative if your keeper gets sent off or concedes too many
goals. (and you have to be careful and make sure your non-playing keeper doesn't suddenly get subbed in himself to ruin things)
