7. Jerry Rice (Football)
He was known as one of the best wide receivers in the San Francisco. Some people even acknowledged him as best receiver of all time! Unfortunately, all this changed ten years after he retired from football when he admitted to have illegal assistance during his beloved football career.
Rice admitted that he used to put adhesive glue on the inside of his gloves which helped him to catch and hold the balls better. Although the NFL banned the use of adhesive glue in 1981, Rice still kept use this illegal substance.
