Paul Powers appears to be preparing for a situation that, from the outside, seems ideal. On Monday, the rising North Hall High senior and four-time swimming state champion, gave a verbal commitment to compete for the 2013 National Champion University of Michigan starting in 2014. Powers, one of the nation’s best sprinters, will learn to perfect his craft in the pool from Wolverines coach Mike Bottom, who is regarded as one of the best sprint coaches in the world.
