Mathias Kiwanuka

Another guy already showing up in a few mock drafts as a possible Browns' first round pick is Boston College defensive end Mathias Kiwanuka. Kiwanuka is 6'7" but only 260 lbs, which means he could probably put on another 20 lbs without losing any of his quicks, of which he has plenty (4.75 forty). The scouting reports on him say he's a natural pass rusher with a lot of upside, but is not yet a solid run defender and has trouble shedding blocks. Depending on who you listen to, Kiwanuka is either the first or second ranked DE in the draft.

Kiwanuka scares me. He is an incredible physical specimen but has a lot of question marks. I'm afraid that the Browns might want to convert a guy like him to OLB, which would make the pick even more risky.

Interestingly, he's the grandson of Uganda's first prime minister, Benedicto Kiwanuka, who was assassinated by Idi Amin in 1972.
