I'm not referring to the state of the roster, save that for the next post grading GM Dave Gettleman. I'm referring here to how well Rivera and his staff have performed related to game prep, in-game decision making and game results.
As you know, the Panthers are 4-0 after a favorable early schedule. The Panther offense is 8th in scoring and 24th in yards per game. The defense is 3rd in scoring defense and 10th in yards allowed per game. The Panthers also have the 6th fewest penalty yards as well.
I'm not going to give you my opinion at this time as I don't want to influence the poll. I'll give you my two cents (hat tip to Neil Spicer) in the comment thread as I'm sure you will too.
