Mustapha plays safety like he is looking for a collision, and that energy shows up all over the defense. He had 76 tackles in only 12 games last season, plus an interception, because he closes downhill fast and does not hesitate when he sees the run. He is more than a reckless hitter, but the coverage side is still catching up to the run defense. Three pass breakups in 2025 is fine, not special, and missing five games matters too. I have him at a seven because the physicality and instincts already change games. If he stays healthy and gets more consistent on the ball, he can become one of the better young safeties in the conference.
Strengths: Mustapha is explosive coming downhill and packs real force into a compact frame. He diagnoses runs quickly, takes confident angles and can match tight ends or backs in shorter areas. His willingness to tackle gives the defense flexibility to use him near the line without worrying about soft edges.
Weaknesses: Deep coverage and ball production are still developing, with only eight pass breakups through two seasons. Aggressive downhill triggers can leave space behind him when an offense uses play action, and the five missed games in 2025 add a durability question to such a physical style.
