- The Cavaliers broke ground on Monday on a new state-of-the-art training facility in downtown Cleveland, according to The Associated Press. Star guard Donovan Mitchell attended the groundbreaking ceremony for the 210,000-square-foot building, which is being funded by team owner Dan Gilbert and is scheduled to open in 2027. “Since I arrived here two years ago, I’ve just heard nothing but how serious Cleveland is about their sports,” Mitchell said. “And seeing it, shows how serious and how much they care about their players and the investment about their bodies. This is going to be huge for the longevity of our careers.”
