Why post the individual pictures of two guys to try to make a point in this argument? That's kindergarten level debating skills.
You know how easy is for me to pick the photo of one of the many overweight or old as MLB players and compare it to a ripped soccer player? Wouldn't mean though, but it would be easy.
On a MLB roster of about 30 players, a little less than half are pitchers. That's a huge handicap. And then you have the Davids Ortiz and Pablos Sandoval.
Let's check the decathlon's compe ions:
100 metres - The fastest MLB player might be faster than the fastest soccer player but the many big liabilities that you can encounter in a MLB roster would bring their average way down.
Winner: Soccer.
Long jump - idem.
Winner: Soccer.
Shot put - I reckon this should be a compe ion MLB players should dominate.
Winner: Baseball.
High jump - idem 1 and 2.
Soccer.
400 metres - lol.
Soccer.
110 metres hurdles - double lol.
Soccer
Discus throw - Baseball
Pole vault - Poles would probably break on MLB players attempts
.
Soccer
Javelin throw - I'm giving all the throwing to baseball although this and throwing a baseball aren't very similar, tbh.
Baseball
1500 metres - yeah well, you know
Soccer
Soccer 7 - Baseball 3
Pretty clean kill, tbh. I don't know how you are going to do to try to spin this more than reasonable assumptions but I'm sure you will give it a try. Afterall, you are the only guy I know arguing that baseball players are more athletic than soccer players.
