Yes, Yes, and No.
Jaylon flashed all of the time because he was a freak athlete and a great tackler. But just being a freak doesn't make you the GOAT (Jaylon was elite, BTW, I'm not saying he was overrated).
Manti was an absolute heat seeking missile his senior year. When he hit you you stopped, and he hit you on almost every play. Add being a captain, 6 INTs (holy cow), and making the entire middle of the field from hash to hash a "no man's land" was something I'd take over Jaylon every time.
I get that people won't all agree on this because we're discussing two all-time greats. But man, I knew Jaylon would come out and make a great play from time to time, and quite often. But literally anytime a team ran anywhere other than directly to the sidelines my reaction was "haha, watch this".
