I absolutely agree but I do understand why some people include him in the welterweight discussion. There are some really huge(and winnable) fights(JMM, Bradley, Broner, Khan, Rios...) out there for him if he just exercised a little (ok maybe more than a little) discipline outside of the ring. He does have a big frame but he's 5'6 FFS, he should be able to make 147.
I don't think Miguel should attempt to get back to 147, he's grown into a solid 154lb'er. I think the siza advantage means he'd beat both guys if the fights happened at a weight where he wasn't half-dead.
