It is not a singular thing, it is the entirety of the officiating that makes it rigged. Multiple times we have shown clear obvious fouls that are not even questionable, the same crew that could see a smidge of grass on that UGA player marking him inbounds, suddenly is blind when it comes to their coaching staff running all over the place. The two different applications of holding when it is happening right in front of the officials, the two different applications of roughing, the two different applications of PI were a significant game changer. Texas lost nearly 80 out of 250 yards in the first half due to penalties, so the game would be closer. With proper officiating the game would have been a blowout win for Texas. But since WRs for Texas were not allowed to block, it modifies how the game can be played. Texas simply wasn't prepared to play a rigged game. The Georgia offense couldn't do shit without ref-assisted or ref-ignored fuckery.
A quick search has one ref fired from the NFL after screwing up and eliminating a team from the playoffs, and another has been suspended for screw ups in the SEC. Two more are Alabama Alum. One is a SCAR alum. Interpret that how you want.
