Interesting pod by Simmons with a former HS teammate of Hayward. He doesnt claim to have any insider knowledge, but vouches for the Hayward/Stevens connection being legit through a story of him in HS. Supposedly Hayward's family were hardcore Purdue fans and even though Purdue offered Hayward a scholarship late, he chose Butler over them because Stevens was the first coach to believe in him.
Then he should have stayed all 4 years at Butler to help Stevens win a national championship.
