Based on reading that rule, the league has obviously seen shenanigans with the kicking balls and imposed a higher level of oversight. It wouldn’t surprise me if they do the same thing for playing balls in the future.
Seattle has a history with doctoring balls as well, as any Cowboy fan will remember.
