reason 4.. the running attack of the Saints is

The Saints rushing attack is quite scary. They have three running backs that can take it the distance from anywhere on the field. They catch the ball out of back field better than most and Reggie Bush is due to show his USC prowess on the big stage. When the Saints were 13-0 they had two games where the offense could not throw the ball at all. The Bills and the Jets did a great job at limiting the passing attack of the Saints. The Saints still won both games by double digits is because they ran the ball down the throat of both of those teams. If you add the dimension of Bush in the return game, this team comes at you in waves. They were 6th in the NFL in total rushing yards. They did not Bell, Bush and Thomas in all 16 regular season games and yet kept defense coordinators up all night trying to figure out how to stop them. The Saints rush defense is average but they play in a run happy conference. They face Carolina and Atlanta twice a year so they are used to facing good ground attacks. However, not many teams are used to facing what they can do on the field. The Colts linebackers are not very good in space and I am positive that the saints will try to take advantage of the lack of cover speed of the Colts backers. Plus if the Colts are not getting a rush on Brees, Brees will have his choice of plays to call.
The Colts did not discover their running game until the playoffs. The Colts ranked dead last during the regular season in rushing only averaging 80 yards a game. Both Donald Brown and Joseph Addai have had injuries this season that have hampered the attack but allowed Peyton Manning to win his 4th M.V.P. award. In the Jet game, the Colts ran the ball better than the Jets and once they were able to control the Jets pass rush and defeat the Jets pass defense, they ran the ball quite well. The Colts really need to run the ball to control the score and tempo of the game. They can shoot it out with the Saints but prefer to do it at their own pace. If Addai can avoid getting hurt or can find some running room, this will make the game quite competitive. In my opinion he is the most important person on the field Sunday. If the Colts feel that they can control the game they will and they will win going away.
In short whoever runs the ball best will win. I think the Saints will be allowed to run the ball because the Colts will want to shorten the game rather than play in a shootout. The only problem with that is the Saints backs make a lot of big plays in games. They don't run 10 yards here, 7 yards here. They run 10 yards and then 30, then 60 and then the game is over!!
