He was going through some personal stuff during the build up and fight with Jones (divorce included). I think his time after that fight he probably he used to deal with those issues, dealing with a disappointing loss to Jones to didn't sit well either. Add that to the retirement thoughts and you got yourself a pretty fucked up Rashad.
He'll be back better than ever, he's a hardworking guy. I don't care to see him drop unless its for a big fight only. He's still easily top 3-4 at lhw imho.
