James, a freshman at Barton and native of Surrey, England, was originally tabbed for the prep school after arriving from across the pond last summer. When that opportunity didn't materialize, he brought his game to Barton, averaging 7.2 points and 7.3 rebounds in the rugged Jayhawk Conference.
"He's a 4/3, and is a shade under 6-foot-8," said Barton County assistant coach Marc Hsu. "He's a tough kid, and he can really shoot it for his size. He rebounds well, he runs and jumps."
James impressed JUCO scout Russ Blake this winter with his utility as a garbageman-type, as well as with his toughness. Hsu believes he has room to grow as a player.
"Once he gets more structure and on a regular weight program, I think he's going to be a great player," said Hsu. "Canisius got a steal, to say the least. I think it's a good fit."
James had entertained a scholarship offer from St. Bonaventure earlier in the process.
Shaun will have three years of Division I eligibility. James joins 5-foot-9 point guard Frank Turner from Atlantic City High School in New Jersey as the program's spring signees.
