Yea it went back 2 weks ago with the pooch kick offs..
47% of challenged calls this season have been overturned. This tells me the refs are doing a crappy job!! and some of the ones not overturned they just say not enough evidence, so in reality probably 55-60% of the calls they make are wrong. PI is not as drastic, but i still say 25-30% of calls are wrong.
