He showed promise his rookie year, but it's been downhill from there.
After several days of speculation as to why the Detroit Pistons forward was not training with the Dominicans, national team coach John Calipari has explained why.
Calipari, who guided the team to a bronze medal last summer at the FIBA Americas Championship and then led the Kentucky Wildcats to the NCAA title, is working out with the Dominicans in Lexington.
Villanueva had a private workout for the Dominican Republic in New York and didn't leave a good impression.
"Charlie was not in good form when we saw him," Calipari said to Deportes en la Z.
"He was overweight, and unfortunately, we could not slow down the entire team and it was a decision taken collectively."
