I don't know about that...wanting to win is one thing...being classless and a sore loser is another...you learn sportsmanship from a young age...plain and simple is that he wants to win, but he is an MOD EDIT SEEK A HIGHER LEVEL!!!
I don't see anything wrong with what he did. He shook the guys hand and moved on. Was he supposed to kiss his feet and congratulate a rookie on a win? Heck no! It's time to get back into the locker room and move on. You just lost the game. If you truly care, you're not supposed to stick around. Especially if that team's been talking trash all week. How do we know Sanchez didn't say something like "We told you we'd beat your sorry arse"?
Edit: Plus, he has like 12 people around him pushing and shoving in every direction. The slow motion also made it a lot more dramatic than it really was.
