Sunday Wildcard Playoff games

How does a guy like Puca Nukua exist ? Like how are you just solid in college , then drafted middle of the pack then DOMINATE ur rookie season in the NFL and break all the records.. helps to get with a good team and a really good QB, but that doesn’t explain it .. How ??
He was judged on that workout warrior 40 time. He’s plenty fast where it counts. Just like another one (not saying he’s anywhere near this guy just sayin’) Jerry Rice. 40 time is so far from the end all be all.
