inputs: hypothesis: Ernie Barnes was an athlete. premise: Ernie Barnes, whose drawings and paintings of athletes, dancers and other figures in motion reflected his first career as a professional football player, died on Monday in Los Angeles. He was 70. The cause was complications of a blood disorder, his personal assistant, Luz Rodriguez, said. Mr. Barnes was an offensive lineman in the old American Football League, playing four seasons in the 1960s for the New York Titans, the San Diego Chargers and the Denver Broncos. He would often say later that even during his playing days, his heart was more in the painting and sketching he had been doing since he was a child.
