What made Jerry Rice so dominant?

I only saw the tail end of his career, and even then, I was young and didn't understand the game as well.

The numbers speak for themselves. I want to better understand WHY Jerry was able to put up those numbers. Every video I can find about "How good was Jerry Rice, really?" just talks about the stats and the anecdote of him catching bricks. They don't actually get into what specifically allowed him to dominate the way we did.

Obviously the longevity is a factor, but his peaks are also insane. So it isn't as simple as "he was available". Likewise I won't buy "he played with Montana and Young" or "he used stickum" cus so did plenty of other guys. Obviously Rice is an outlier or outliers, I want to know why.

Was he a just a way better athlete than everone? The numbers I can find on his measurables aren't particularly impressive by today's standards.

Was he that polished of a route runner? I don't have All-22s of the guy but when I watch highlight tapes the footwork doesn't jump out on me. I feel like there's lots of other guys who have more precise footwork but aren't one tenth as dominant as Rice.

Were his hands that much better than everyone? How does he compare to someone like Fitz as far as drop stats? If his hands were that great, what made them that why? Did he have huge hands? Or just great hand-eye coordination?

What my him so great after the catch? Again, watching footage, he doesn't strike me as crazy elusive. But then he just seems to slip by everyone? Is it just expectional awareness that allowed him to make it look easy compared to other more dynamic looking playmaker?

Speaking of spatial awareness, was it his ability to use leverage? Randy Moss was fast and big but so were plenty of other guys. His career I watched a lot more of. I understand that how he made the most of his athleticism by using leverage to manipulate defenders. Was the same true for Rice?

I want to be very clear that I AM IN NO WAY WHATSOEVER DOUBTING THAT JERRY WAS REALLY THAT DUDE. I just want to understand why he was so much better than everyone.

There's other guys, of the same position, of his era or even earlier where I can see from highlights oh this guy was +++ at this skillet. Irving had an unusual combo of play strength and precision that made him exception in tight spaces. Chris Carter had insane body control could high point a ball like crazy. What was Rice's thing? Was he just really really good at everything but not a complete freak at a couple of things? So well rounded that it is hard for any one trait to rise to the top?
