Does the current era of welters pale in comparison to the last one?

What’s your verdict on this one? I used to think we’re just in awe of how the Floyd’s and the manny’s from the previous era were beautifully marketed by HBO and showtime (esp in the social media age) that we miss the greatness and potential of the new comers. But few years had passed since their time and come to think of it. Cotto and Margarito were not even as highly regarded as Spence right now at welter but 10 years ago they would have beaten Mikey Garcia who climbed two weight classes like a drum at welter. Even Prime Hatton would have outmuscled and wrestled Mikey to submission at welter. Fossil Mosley 10 years ago would have dropped past prime Khan like a bag of potatoes. I hope I’m wrong but the window for the current welters to acquire greatness as the prev era, let alone the eras before that, is fast closing as most of them are already in their 30s. Thoughts?
