Oscar is struggling to make 150

[SweetPea]

If Kelly Pavlik and Jermain Taylor could make 160 then Oscar can get down to 147.

Except Pavlik and Taylor are much younger than Oscar. Do you think those guys will be able to make 160 when they're 35 years old (Oscar's current age)?
When Oscar was in his 20s like Taylor and Pavlik, he could make 147 easily. But he's not young anymore. He's 35 and has been fighting at 154 or above for 7 years.

P.S. I know Mosley was able to drop back down from 154 to 147, but he's shorter than Oscar. Also, Shane looked overly muscular at 154 (and looked like he'd be better at 147), whereas Oscar looked natural at 154 and comfortable there.
