Alvin Brooks swore to himself he’d never go back. Too many bad memories. Too much University of Houston business left unfinished, unresolved. Brooks told people he simply didn’t see how he could possibly go back to the school that gave him his big chance to become a college basketball head coach. He was so sensitive to how awry that five-year stint went, he made it a point to keep under wraps his friendly relationship with first-year UH athletic director Mack Rhoades.
