The biggest reason he won’t be a 5 star is his size. Those ratings are projecting NFL potential, or at least 247 is rated that way. Elite speed could make up for height, but Isaac needs another 2″ to have 5 star potential without that elite speed.
His stats and play against high level competition could’ve easily erased any camp competition results like Elite 11.
I imagine he’ll finish around a 93-94…
