 Football, basketball, or hockey? Maybe we'll throw soccer in there as well. The hardest sport to play? I would say hockey because you have all the movements of being like a field animal where you can run around and do those things, but you're in the water, so it requires you to tread water the entire time. There's no mandatory break where you're just sitting and thinking and chilling. To me, I just think that's hard. I think they'll be, man, worrisome about the body.
