2. He is moving the ball this year
In the past, you would see games where Andy didn’t even make the 200-yard mark in games. That hasn’t been the case this year. He has been over 200 yards in every game this year, including a stretch of 4 straight 300 yard games. He is in the top-10 in the league in passing yards, and is well on his way to over 4000 yards, close to 4500 yards. He has thrown to damn near everyone he can throw to at this point, and it has paid off.
3. He is a lot better on his feet than one might think
We saw it against Baltimore a couple of times, as well as several times this year and throughout his career so far. Andy Dalton can run for a first down if need be. When there is no other option, he is willing to run the ball (quite unlike that one QB that preceded him).
