Lots of people think Flacco = Freeman (I agree). They are basically the same player, one just has the benefit of having a better defensive squad. People will disagree and say Flacco is better because he has been more "consistent" and always keeps his interceptions down. But they will also deny or belittle the theory that MOST quarterbacks do better with a better defense. When you have a sorry defense, your quarterback is/should take more chances for the small fact if you don't, you get blown out so it's a giving their interception rate will get higher. Check qb stats along with defense, they correlate. Here are some stats I picked out..... Look at Defensive Points and Yards rank then Wins and Loses. It's very, very telling.
NO QUARTERBACK IS GOING TO GET US TO WIN IF WE DON'T IMPROVE OUR DEFENSE
