I remember when Thiago Alves was making his LW debut, and I think it was possibly Ariel who asked him "Have you done a test cut"? And Thiago shrugs it off like it's no big deal. Then he misses weight, loses, and is immediately back up to 170.
We see this shit happen so often, and we know from Pettis that even it being a title fight doesn't make any difference in cutting those final few pounds.
Why risk having an opponent miss weight in a title fight? There's so few active champions as it is, show some respect and have the challenger win a fight in the weight class before jeopardizing an active champion.
This company doesn't learn and neither do fans.
