I think he might have top 15 power even at 154, honestly. The way Joppy reacted to his shots was ridiculous.
I don't think anyone would argue against him being a top 10 puncher at either 147 or 154, though the Joppy fight was at MW.
At 147, only Hearns, Cuevas, and Robinson were bigger punchers. At 154 only Hearns, and Jackson were bigger punchers.
I think he belongs in the top 5 at both 147 and 154, and as proven in the Joppy fight (as well as against Cherifi and Mayorga) his power was still pretty lethal at 160.
Trinidad's power ranks alongside the hardest hitters ever at 147 and 154. No question about it. Opponents were never quite the same during a fight after Trinidad sustained heavy artillery on them. You had to have an exceptional chin to stand up to his power, which was devastating when he hit opponents flush. He short circuited his opponents when he landed of them.
Trinidad's power got better as he moved up. Trinidad was more powerful at 154, and 160, than he was at 147. Trinidad was always considered as a hard puncher. Trinidad just didn't turn heads the same way at 147, as he did the next two divisions above. It is harder for me to gauge his power at welterweight.
Anyone ever see Trinidad's chilling one round KO over iron chinned ultra ballsy Troy Waters? Norris laid into Waters with absolutely everything he had for multiple rounds and and couldn't even remotely match what Trinidad did to him with, what, a handful of shots?
Trinidad's first apperance as a jr middleweight. I'm pretty sure it was at Madison Square Garden. Yeah, and he buried him quicker than Norris did. Although we are talking about Waters 5-6 years after Norris fought him.
