Tiawan Mullen
. We're projecting long term, so we always have to take physical attributes into account and Mullen lacks size. That said, he’s proven he can cover bigger wide receivers and it’s not as though there haven’t been smaller defensive backs in the NFL. He’s always caused an internal debate inside of my head because I’ve seen him shine up close but I also know that size is a massive factor at the next level. It’s why Mullen has spent his high school career to this point as a high three-star and hasn’t been able to break into four-star territory."
