"It's not an insignificant piece of evidence, but the key to any collusion case is having evidence that the owners agreed not to sign Kaepernick because of his demonstrations during the anthem," Gabriel Feldman, director of the sports law program at Tulane University Law School. "There may be evidence that an owner decided not to sign Kaepernick because of his demonstrations, but it's not evidence that there was any agreement between multiple owners not to sign him. Even if the president did convince some individual owners not to sign Kaepernick, the missing link is an agreement."
