Miller was kicking terrible last season, he went on IR with an injury, I dunno if he will be better next season, but right now i'd rather have Sauerbrun.
Sauerbrun was the co-MVP of the San Diego game. Without his booming punts in the 1st half the Pats may have been in a hole they couldn't have recovered from. Keep him. Let bygones be bygones. Guy has said and done all the right things so far. Clearly has one of the best legs in the game.
