Looks more athletic in that clip than any of Jevon’s highlights. But like you mentioned, he was also old for his grade.
Jevon’s a little taller than MPJ was as a freshman, though.
Wouldn’t surprise me if he ends up more of a Mitchell Smith type than either of his brothers. Jontay’s the only Porter kid (so far) who wasn’t rail thin, and MPJ was the only one who was a truly elite athlete (as far as I know; I’m not sure how the two oldest sisters compared to their peers athletically).
