The Kansas City Chiefs had a number of tryouts recently, including a former track and field star from England. According to Aaron Wilson, the Chiefs hosted DE Lawrence Okoye, DT Derrick Lott and RB Gus Johnson.
Okoye is the headliner here and not just because the Chiefs have had success with that name before. He is a former track and field star who competed in the 2012 Summer Olympics. He entered the 2013 draft despite never having played American football. The 49ers ended up signing him after the draft and he stuck there for a couple of years.
