Former Purdue center Matt Haarms announced his commitment to BYU.

Haarms is ranked as the nation's top available transfer, according to ESPN.

"I came down to those three schools, and at that point I was just looking at everything. I could weigh the pros and cons for hours on end, but I needed to make a decision on where I felt I could be the most successful and where I could be 100 percent mentally committed and where I truly trusted them," said Haarms, who chose BYU over Kentucky and Texas Tech.

The 7-foot-3 center averaged 8.6 points and 4.6 rebounds for the Boilermakers last season.

His decision to transfer reportedly caught the team by surprise.
