Isaiah Brock, who became a standout defensive player for the Oakland basketball team after serving four years in the United States Army, is transferring to Grand Valley State.

He made his decision last week.

Because Brock is transferring from a Division I program to a Division II program, he will be immediately eligible. Brock has two years of eligibility remaining.

He is the second player Oakland is losing to transfer, after sophomore big man Chris Palombizio decided to look elsewhere.

Brock, 6-foot-8 and 191 pounds, is second all-time in blocks at Oakland with 158, 86 coming this past season. He also averaged 8.1 rebounds a game in 2017-18. His first year at Oakland, he earned Horizon League all-freshman team recognition.

Brock arrived at Oakland in the summer of 2016, after he met Kampe during a coaches' goodwill trip to Kuwait in 2015. Kampe and Brock met one night at Camp Arifjan, and Kampe was so impressed, he told Brock that when he got out, there'd be a roster spot for him with the Golden Grizzlies.

Brock, a Maryland native, took him up on the offer, but was briefly benched by the NCAA, which cited his five-year-old high school grade-point average as being insufficient for competition.

After the community, including Congressman Mike Bishop (R-Rochester), rallied around Brock, the NCAA relented in October 2016, shortly before the season, and Brock went on to be a star for the Golden Grizzlies  even though Kampe always insisted he had no clue when he offered Brock the roster spot if Brock even would be good enough to play Division I basketball.

Brock, 24, briefly left the Oakland team last summer, saying he was done playing college basketball and wanted to get on with his life and career. But he came back, and was an impact player again.

Brock, who also served in Afghanistan and had a decorated career in the Army, joins a Grand Valley State squad that was 14-15 this past season, including 9-11 in the Great Lakes Intercollegiate Athletic Conference.

Brock didn't immediately return a call from The Detroit News seeking comment Wednesday.

This is a big loss for Oakland, which already was bidding adieu to several key seniors, including Kendrick Nunn, Martez Walker, Nick Daniels and Jalen Hayes.

The Golden Grizzlies recently got a transfer commitment from Eastern Michigan's Jordan Nobles, a 6-foot-9, 195-pound forward from Canton who, as a grad transfer, will be immediately eligible. Kampe also has put together what experts consider a quality recruiting class.
