I'm guessing your top 5 grade is based on "Is this guy a Myles Garrett / TJ Watt / Aidan Hutchinson type of prospect?"
That he isn't. However, given the lack of that type of player at any of the 4 premium positions (QB / WR / EDGE / LT) (maybe Reese?), where does that put him specifically in this draft?
If I compare him to the EDGEs from last year's class, he feels to me like a juiced up version of Ezeiruaku. Better size, better athleticism and better production through his college career. He would've probably been a 2nd round pick last year and, with the season he has had, he feels to me like a better prospect than Mykel Williams, Jalon Walker and Shemar Stewart.
I think a range of #5-#10 in this class is acceptable for him.
