tanacious

persistent in maintaining, adhering to, or seeking something valued or desired
describes rugby, players move small amounts to score points
it looks like it would be fun to play, your never running that fast so your not going to get hurt as much compared to football.
speaking of tenacity, the man who introduced me this sport. rugby is in his vains, evident in his tenacity for the Lord and his stature. please to know him

they do this cool jumping thing

...whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.
