All is good in theory but the reality is there is a shortage in refs already. If you boot the ones you have because of an obviously biased eval, then we would have even less refs. Lack of refs means shortage of matches. I agree with formerref, adjust to the style of the match. Sure, refs are wrong a lot but at the end of the day it is the coaches job to prepare and adjust during match situations.
As a coach, I definitely look at the ref sheet when formatting a game plan. Especially with high school boys, who can get hot headed. If my center mid is a hot head and I have a ref who calls it extremely tight in the middle, I may move him to another position to save him from getting a card. It is all relevant, not everything can be blamed on them. But I do agree, they make their share of mistakes.
