I played rugby for one year and found it to be the most physically challenging - being in the scrum was similar in intense physical exertion to wrestling - but with more bodies! Add in running non-stop up and down a soccer pitch, and tackling or attempting to break tackles like football without the blocking or the constant huddles. Madness.
I second this. As a hooker ( I know) for four years, I found nothing as taxing, or as joyous. Constant movement, constant shifting focus, all the while yelling "thank you, sir" when the single official calls a foul.
Apparently you can only vote once (per device/OS). DT is killing Rhonda Rousey in the quarterfinals 59% to 41%
