I've watched that play to Crabtree more and more today... and interference could definitely been called. The reason I don't get too wound up about it is because it looked like Crabtree was pushing off a bit on Smith's helmet. Plus, the refs seemed to really let the defensive players have as much play as the receivers all game long. Then again, I can understand here it's for the championship title.
Again, maybe because its the Super Bowl, but I was really surprised there were no ejections in not one, but TWO fights during the game. Put that on Boger, also.
