Salido was clearly weight drained...

Having a significant weight advantage can be very serious; hence the reason why weight classes exist. I don't know for certain if Salido did it on purpose or not, but his size was an obvious advantage during the fight. Salido was crashing in with reckless abandoned. I'm willing to bet that had he made the limit and weighed within the normal range on fight night, the fight would've been completely different.
