rugby, soccer and hockey...... in that order are the most grueling sports...
rugby...everything soccer has to offer....tossed in with no pads brutal football
soccer...crazy running, never stopping, heart pumping makes me wanna die thinking about it
hockey...skating in multiple directions, handling pucks while dodging large speeding people trying to knock you down and still shoot the puck is pretty taxing
football is a rough sport...takes extreme athleticism...very few people can play football at a professional level but there are many breaks. even in high school football you still get a little bit to sit in a huddle and catch your breathe.
edit::: for what its worth....Justin Tuck is faster than strahan. i watched him run down tomlinson to save a touchdown when tomlinson was already 20 yards ahead....crazy
btw im an eagles fan
