That one was a broken collarbone. He also re-injured it a few months later riding his motorcycle which delayed his return.
He can fire up any crowd.

Same with getting heat when he was working as a heel. He works the crowd like very few can during matches. He knows how to fire up a crowd or how to get them to boo him, whether it's a smark crowd or mark crowd. He's a master at that.
Maybe he is and maybe he isn't because he has far more dull matches where he doesn't do any of that than he does ones like that. Lots of guys can fire a crowd up here and there. Orton doesn't and never has done it consistently...possibly because of his complacency issues but even when he does, his matches aren't exactly entertaining. He works a pretty clean and crisp match and has a great finisher but there isn't much excitement with his work.
Most fans are looking for a reason to get amped in those situations...the fact that he has to look to work the crowd to draw interest in a lot of his matches is a problem in itself because his work isn't exactly flowing with energy and anticipation on its own.
