It was a brave effort but he just isn't big enough to damage Welterweights. Fai rplay, PBF proved that no one can touch him and I wouldn't blame him if he called it a day. Ricky FFS, go back to 140 and stay there. You are giving too much away stepping up. At 147, he would still beat most due to his talent but giving away your main advantage which is strength is ludicrous.
Not really Hatton isn't "naturally" 180lbs, he simply eats so much shite, so he's podgy to put it kindly If he ate what you'd expect a top class boxer to eat he'd be much closer to the junior welter limit
He only walks around at 180 because he gauges himself and is overweight. Thats not what his natural weight is and should be. His actual natural physique is more akin to 140. Theres a difference!
