Calling “Sir Charles” the “Round Mound of Rebound” is no understatement. At only 6’6, Charles is the shortest player to ever lead the league in rebounds. What he lacked in height, he more than made up for in weight, tipping the scales at a whopping 252 pounds during his playing days. (AP Photo/David J. Phillip)
