Mapu has been praised for his versatility, but he might need to prove he can excel in at least one department -- whether in run support or in coverage -- at the next level. He lacks short-area athleticism and long speed, so his man coverage might be limited to tight ends. He is highly instinctive from short zone and is a very willing hitter when playing near the box. It won’t be a surprise if Mapu adds weight and locks in as a backup weakside linebacker in a 4-3 defense as a pro.
