Manning is one of the best quarterbacks of all time. He is also on the down side and may never be the same again. While Tebow isn't a very good quarterback now. He is a great leader and took a team that had not one much to the playoffs. The player to go after is Mario Williams. He is a game changer going into the prime of his career. He will be expensive and we are already paying Doom a lot. He is also a much better player than Doom and will be a great tandem with Miller for years to come. Signing Super Mario will take a weakness and make their D-line a strength. Signing Manning will be an upgrade but only if an over 30 quarterback with 4 neck surgeries can stay healthy.
