Yep, and he got his guys to believe in him because of it. Nothing like a player willing to sacrifice himself for the team. As long as you're not doing it in a dumb way lol, i.e. taking on safeties head to head when sliding would be in the best interest (not at the goal line of course lol).
Yeah like when RG3 got injured, I thought that was a injury that shouldn't have happened. He was so close to the sideline he could have just ran out and instead slide and nailed in the head.
And thankfully Luck is very aware and doesn't put himself in too much danger. He is very smart when after he gets the first, he doesn't try move it more downfield, he just goes out of bounds.
