Umpiring bias HAS to exist with how the rules of the game are outrageously subjective. It's impossible for bias not to exist.It absolutely amazes me that (mostly) neutrals and a few Tigers state that there is no umpiring bias as it couldn't possibly exist.
To simply prove there is - you don't need to watch a Richmond game, watch a GWS game. Watch how Toby Greene gets treated by the umps and then come back to me and tell me that he gets treated exactly the same as every other AFL player.
Carlton are near top of the umpiring ladder (not because Cripps gets away with throwing it) but mainly because their 2 key forwards Curnow and McKay get royal service from the umps. Are they directed to do so? What other explanation could there possibly be?
There is a MASSIVE umpire agenda.
That being said, I think it's highly unlikely that there is a nefarious umpire agenda specifically against Richmond.
Umpires have an impossible task. Every key rule is way too subjective. They're forced to over-rely on what they know about how each player plays - these directions undoubtedly lead to bias. We know this from how JR8 was treated relative to other key forwards.
This is a result of shit rule design by the AFL, more than unskilled umpires. The integrity of the sport doesn't matter to the AFL. We increasingly know this from the reactionary way the AFL approach EVERYTHING. It's a professional sport run by spinsters.
Blame the AFL, not the umpires.
