Theare coming off of an impressive 34-13 road victory against the. They are back in action on Sunday with their home opener at Gillette Stadium against the. Here’s a preview with my five keys to the game that I hope will lead to a Patriots victory.The game will be shown live Sunday on WFXT-TV at 1:00 PM EST. You can also listen to the game on 98.5 The Sports Hub in Boston.The Cardinals are coming off of an opening game victory as well as they beat the20-16 at home. It was not an attractive victory for the home team, but a win is a win. The Cardinals should prove to be a tougher test for the Patriots as they do have some talent on both sides of the ball.On defense, this team has several players you should be watching for on Sunday. The defensive line is very good, and led by defensive endsand. Patriots offensive tacklesandwill have their work cut out for them.Patriots fans might be familiar with middle linebackerwho was briefly with the team, but overall the linebacker unit is strong. This front seven as a whole could be handful as they run the zone blitz defense made famous by theThe Cardinals secondary is led by strong safetywho happens to be one of the best in the game. The cornerbacks are also decent, and not to be overlooked either. This unit is solid and will be a challenge for the Patriots.On offense, this unit is not nearly at the level of the defense. The first issue is at quarterback wherewon the starting job in the beginning of the season over. However, Skelton is dealing with an injury, and reportedly the Patriots could see Kolb this week as the starting quarterback for the Cardinals. We probably won't know for sure until the final injury report comes out on Sunday.Regardless of who starts at quarterback, both options for the visitors are average at best. To add insult to injury, the offensive line for the Cardinals is pretty poor, and the Patriots front seven should be able to take advantage of this group.However, the Cardinals do have some talent at the skilled positions led by one of the best wide receivers in the game, and that is. You should expect to see Fitzgerald double-teamed the majority of the game. However,is a nice option at the other wide receiver position.At running back,is a talented back, but I have doubts on his effectiveness in this game. He could have serious issues finding holes to run through.The Cardinals are a step up in competition, but their issues on offense could really hurt them in this game against the Patriots. I expect the visitors to make it a game for awhile, but eventually the Patriots should pull away with the victory.Here are my “which I believe could play a role in a potential victory for the Pats.andwill be needed to limit the damage that Dockett and Campbell can do with getting after the quarterback. If they can do a better job than they performed against the Titans in pass blocking, the Patriots could be on the road to a victory.The Cardinals do offer a challenge toandbut they should be able to find mismatches in the secondary.This is the opponent for the Patriots defense to attack, and I expect to seeto have a big day. Also, don't be surprised to seebe a factor on Sunday as well.There are a few dominant wide receivers in football, and Fitzgerald is definitely one of them. If you can limit the damage from the ball going often to Fitzgerald, it could really change the game.Special teams are always important, but they have a big job on Sunday against Peterson. Whether it is directional punting or the coverage itself, this unit needs to do a great job on Sunday. Peterson has the ability to change the game with one punt return for a touchdown.I am feeling confident that the Patriots should be able to win this game, and think it could be won in the trenches on both sides of the ball. I am hoping the Patriots lineman win their battles, and lead the team to another win. I see the Patriots winning this game 31-17 against the Cardinals.What are your predictions?
