Leonard Williams, a defensive lineman from Mainland High School and USC, is expected to be selected in the top five picks of the upcoming NFL draft. At 6'5" and 302 pounds, Williams has an ideal size and athleticism for the NFL. He overcame obstacles like being told he was too heavy to play youth football to become a star at Mainland and USC. On Thursday, Williams is poised to realize his dream of being drafted in the first round and becoming just the fourth local high school product to achieve that honor.
