The Chicago Bears host the New Orleans Saints on Sunday (1 p.m. ET, FOX).

ESPN analysts Ron Jaworski and Sean Salisbury break down the game plans of each team.

JAWORSKI VS. SALISBURY

Jaworski on the Saints The 2-0 New Orleans Saints are playing rock-solid football. I covered their Week 1 game in Tampa and spent time with the Saints' coaching staff. They thought the team would come together around midseason. Instead, the team gelled quickly. Offensive coordinator Mike McCarthy deserves credit for putting the offense together, despite having a work-in-progress offensive line, a new starting running back in Deuce McAllister and rookie wide receiver in Donte' Stallworth. Defensively, the Saints lost two Pro Bowlers -- Joe Johnson and La'Roi Glover -- in the offseason, but defensive coordinator Rick Venturi has them playing within the scheme and playing together. Overall, the Saints are playing as well as any team in football. In the first two weeks, they have beaten two playoff teams -- Tampa Bay and Green Bay. And they have already put their signature on the season heading to Champaign, Ill., to play the 2-0 Bears. Five keys for the Saints: 1. Explosive plays: At the disposal of quarterback Aaron Brooks, the Saints have tremendous offensive weapons at wideout in Stallworth, Joe Horn and Jerome Pathon. While Pathon is more of a possession receiver, Horn and Stallworth are big-play guys. The Saints must try to keep explosive plays as part of their game plan, something I know McCarthy will do. 2. Bust Deuce loose: The Saints must feed McAllister the ball and make him the offensive focal point. If he gets his runs, the Bears will be forced to keep an eighth defender near the line of scrimmage, opening up big-play opportunities downfield. McAllister has been multidimensional. While Ricky Williams would give the Saints five or six yards, McAllister can give them 15 or 20. He has proven to be an explosive, quick, strong-willed runner who doesn't go down easily.. 3. A fine line: While people dwell on Brooks, McAllister, Stallworth and Horn, the key to their success has been the offensive line, anchored by Kyle Turley, who has moved from right tackle to left tackle. Judging from the coaches' tape I've seen of their first two games, the line has played well and appears to be on the same page. Rookie LeCharles Bentley has been awesome at right guard. 4. Derail the A-Train: Against the Bears, teams need to first stop the run. Their foundation is to run the ball and then get their play-action and short passing games going. The Saints must take Anthony Thomas out of the game as soon as they can. The Saints play aggressive defense under head coach Jim Haslett, and defensive tackles Norman Hand and Grady Jackson need to continue playing terrific football up front. 5. No big plays allowed: The Bears will try to get the big play to Marty Booker, who has been their go-to guy. While the Bears like to run the ball, they won't score many points with just that approach. So the Saints would rather give up a few yards on the ground instead of giving up explosive plays to Booker through the air.

Salisbury on the Bears The 2-0 Chicago Bears are a confident team that believes it can overcome anything and win every close game. They picked up where they left off a year ago, when they went 13-3 and seemed to pull out every victory in either overtime or the closing minutes. Even a temporary move from Soldier Field to the University of Illinois in Champaign hasn't slowed them down. But when a team wins as many close games as the Bears do, it's not luck. Coach Dick Jauron and his staff do a great job of preparing their team and establishing a winning mind-set. The Bears rely on physical, mistake-free football on both sides of the ball, and no two players symbolize their toughness more than Anthony Thomas on offense and Brian Urlacher on defense. This week, however, the Bears have to overcome another key defensive injury to Ted Washington, who will miss at least 10 weeks. Chicago may need some more late-game heroics to hold off a hot Saints team. Five keys for the Bears: 1. Limit the Big Plays: Aaron Brooks, Deuce McAllister, Joe Horn and Donte' Stallworth are all big-play guys. Three of the Saints' six offensive touchdowns have come on pass plays of 32 yards or more, two of them to Stallworth. The Bears defense needs to tackle well, limit the "chunk" plays (those that gain 20 yards or more) and make the Saints plod along, gaining three or four yards a time. Chicago can't allow the Saints to explode for six or seven big plays. 2. Air Attack: Defensively, the Saints are big up front, especially in the middle with Grady Jackson and Norman Hand. The Bears don't want to run uphill and get into a bang-it-out football game with them. They need to attack through the air first, stretch the Saints out, and then pound the run with Thomas. Jim Miller has weapons outside with Marty Booker, Dez White, Marcus Robinson and David Terrell. Throw the ball and attack through the air to set up the run. 3. Don't press your luck: The Bears keep winning close games. Last year they won eight games by seven points or less. And in their first two games, they have won by a combined total of five points. Although the Bears don't win games by chance, the outcome will eventually fall the other way. The Bears need to create some space by scoring points. They would have lost to Atlanta last week if Jay Feely hadn't missed a 45-yard field goal with 56 seconds left. The Bears won't be able to win every close game. 4. Stop the run: McAllister has developed into a great running back. The Bears defense needs to shut down McAllister and to not let him get 25-30 carries. The Bears are physical enough up front to limit the run and make the Saints' offense one-dimensional. By doing that, they'll prevent the big play with the run and force them to work a short passing game. Make them pass and then tackle them for short gains. Don't let the Saints get in a rhythm running the ball because McAllister is a big-time player. 5. Limit the Short field: The Bears can't give the Saints a short field. If the Saints only have to drive 30 yards for a score, they will pound the ball and do whatever they want. Make them go 70-80 yards for touchdowns or field goals. If the Bears turn the ball over, they need to do it on the Saints' side of the field.
