Unlike football recruiting, which has remained somewhat regional, the best basketball teams these days draw players from everywhere. Thanks to summer leagues, the best players congregate in April and July showcases in a few cities near large airports in front of coaches from across the country. Even the 10 or 12 most prominent programs in the country — a classification that definitely includes Michigan State — sign only a combined few dozen players every year, so they can afford to chase after the best.

The in-state talent comprising 62.5 percent of the Michigan State roster, then, stands out.

At public-school programs similar in pedigree to Michigan State, this ratio tends to be much lower: 3 of 15 at Kansas; 1 of 12 at Kentucky (or two if you count the walk-on Brad Calipari, the coach’s son, who went to high school in New Jersey); 6 of 17 at North Carolina.

Nor is this some Big Ten occurrence. At Ohio State, the equivalent figure is 6 of 14. At Wisconsin, it’s 4 of 18. At Indiana, it’s 7 of 17.

In fact, of a semi-random assortment of 20 prominent state-school basketball teams, only Washington’s and Georgia’s had instate-to-out-of-state ratios similar to Michigan State’s. Only 6 of the 15 players on the Red Raiders roster Michigan State will face on Saturday are from Texas.

The trend is not new: For years, Michigan State’s biggest stars have almost all been Mitten Staters. Winston was Michigan’s Mr. Basketball at the University of Detroit Jesuit High School. Bridges, who was the 12th overall pick in the N.B.A. draft last year, is from Flint, though he played high school basketball in several states. Denzel Valentine is from Lansing, Draymond Green and Jason Richardson from Saginaw.

Dane Fife, another Michigan State associate head coach (and a former Michigan Mr. Basketball), is the son of a longtime high school coach in Clarkston. He said the kinship among players in the locker room (which also includes two Ohioans and one player from Indiana) has real competitive advantages. “There is a sense of loyalty not just to your school,” he said.

The biggest drawback to focusing on Michigan basketball in recruiting is the condition of Michigan basketball. It has seen better days.
