The Michigan football team could potentially add as many as 28 recruits come signing day, and is not bound by a 25-player maximum, according to Brian Cook at mgoblog.com.
Previous radio reports, according to Cook, had said the Wolverines could sign no more than 25 players. But the Big Ten's director of compliance issued an email saying there was no rule that would mandate schools only sign 25.
