C'mon, seriously? Not knocking baseball, but a baseball game is more skill based than a body workout. To your point, I can see if you are talking about a pitcher or catcher, but the rest are standing around or sitting for the majority of the time. And a tennis player is moving throughout an entire match. Maybe baseball player (other than pitcher or catcher) is just wiped from merely wearing that uniform out in the sun and heat sweating all day. Guess I can also see your comparison being true if comparing the pitcher & catcher to the hockey player who sees no pp or pk time and only plays every 3rd shift. Generally speaking though, imo, there's no comparison. Know an elite level baseball player who playes games all day & often doesn't even need (or takes) a shower after the games before he heads out to play with friends.
A good lax, soccer or tennis player is going to exert themselves more than a baseball player would.
Fact, not opinion.
Agree with above.
I'm not too sure about "...like most NHL and other pro athletes he is a freak athlete." Look at the NHL Draft Combine scores and it is pretty amazing how few of the scores are all that good. It would be interesting to compare some of the scores across sports but I think very few qualify as top decile high school athletes let alone 'freaks.'
