Which sport is harder to play, football or baseball?

My friend, who played football in high school, and I, who played baseball, got into an argument over which sport is harder to play/succeed at. He insists football, while I insist baseball. I conceded that you need to be more physically adept to play football, except I believe that baseball is more mentally taxing and requires more finesse and mental awareness. So reddit, who's side are you on?
