Back in the day, for some reason, I enjoyed watching on TV the Cornhuskers of Nebraska run their vaunted triple option play in what was then the Big Eight (today I think it's the Big Twelve). In that Nebraska squad was a Kenyan guy playing the I-B, who'd come in to spot the starters, usually in the waning moments of the game (garbage time), when the Cornhuskers were up by twenty plus points or so. The guy's name was George Achola, I believe.
As for this young guy, Rees Odhiambo, he has the three attributes that'll serve him well as an OL in the NFL: good intelligence, athleticism and strength, plus the right height. Checking his workouts on YouTube, he seems to have the agility that will come in handy when he has to fend off against the JJ Watts, Ndamakung Suhs and the Von Millers of the world as he protects his QB.
