Cant you feel the tension? Which side will he choose? Good? Or Evil? Will he... aw who am I kidding?! I really am not fussed. TNA has completely lost my attention!
The fans are not necessarily chanting for Russo's firing per se rather they can see through the crappy booking and gimmick overload is detrimental to the wrestlers and their ability to have decent matches when being held down by stupid gimmicks like this Tuxedo Chain match.
Since Russo is famous for that style of booking and is on the TNA creative team, they use him as the main point of reference to vent their displeasure. However he is is just a cog in the TNA machine, one that isn't delivering what the fans want - hence the chants.
