Well that sucks, because however mediocre he was at SS (1+/2-), he is bound to be worse now.
For what it's worth, my FI coach was 79. Not good, not terrible. But as tec said, I don't think that affects range, and it certainly doesn't affect dur.
And I could be wrong, but does a coach affect a player's decline, or just his development?
Anyway, thanks for the responses. Maybe it was random variation.
