I don't think that he should have taunted Crabtree after the interception, but then again, we do not know the history between them.
However, I don't have a problem with his post-game interview with Erin Andrews. The interview was just moments after Sherman made the biggest play of his career. His team had just beaten their division rivals and was headed to the Super Bowl. Furthermore, he had a history of trash talking. Did anyone really expect him to be anything other than emotional?
He didn't swear, and he didn't threaten Crabtree. All he did was show some emotion, which is what we want to see.
Some people argue that he is setting a bad example for our children. If this is true, then parents should use this to teach their kids the correct way to behave. It is ultimately the job of the parents to teach their kids right from wrong.
I'm not saying that Sherman handled the situation perfectly, but I don't think we should attack him for his actions.
