Dartmouth basketball players vote Tuesday on whether to form a union. (AP Photo/Jimmy Golen)The Dartmouth men’s basketball team voted to unionize Tuesday in an unprecedented step toward forming the first labor union for college athletes and another blow to the NCAA’s deteriorating amateur business model. “Today is a big day for our team,” said Dartmouth juniors Cade Haskins and Romeo Myrthil, who have led the effort. The case could also wind up in federal court, which would likely delay negotiations over a collective bargaining agreement until long after the current members of the basketball team have graduated. ___AP college basketball: https://apnews.com/hub/ap-top-25-college-basketball-poll and https://apnews.com/hub/college-basketball
