There has been so much focus on the quarterbacks this week leading up to the AFC and NFC championship games, and rightfully so with all the talent that will be on the field -- but let's not forget about the defenses. Somebody has to try and stop the quarterbacks. NFL Playoffs In and in the NFC and and in the AFC, we have a star-studded field of pa sers -- including seven Super Bowl rings combined. That will make for big challenges for all four defenses this weekend, and the two that handle it best will be going to the Super Bowl. On paper, we should expect to see a lot of scoring in the NFC, le s in the AFC, although Benny Snell Jr. Jersey with Roethlisberger and Brady you never know. Here's a look at all four defenses as you ready for Sunday's games: Young player to watch Cornerback : He took over as the starter when was lost for the season with a torn pectoral muscle. He's done a nice job, even if he isn't as good as Trufant. He was good in man coverage last week against the Seahawks, although he did give up a long pa s completion to on a cro sing route. Collins can sometimes drift in zone coverage, leaving a void, so keep an eye on that this week. If receiver can't go, that will be a big help to Atlanta secondary. is the other starting corner, and he has more experience. I would expect the Packers to attack Collins and nickel corner . Who the Packers should attack The Falcons sometimes seem to lose guys in zone coverage, which allows easy throws to open receivers. That's what happens when you have young players on defense. The Falcons start three rookies in linebackers , and safety . They are all fast and aggre sive, but that can lead to problems in coverage at times. Against Rodgers, that can lead to big plays. They also have to plaster their receivers when Rodgers does get out of the pocket. Defensive key Can they Cody White Jersey contain Rodgers and stop him from getting outside to make plays? Rodgers is outstanding at extending plays, which will put a lot of pre sure on the edge pa s rushers, especially , to keep him contained. The Packers are great at getting away from defensive backs when Rodgers is outside the pocket. He has to be contained. Beasley didn't get a sack last week, and that can't happen here. Young player to watch Cornerback : When the Falcons beat the Packers 33-32 in Week 8, Gunter was a signed the duties to cover a lot in man situations. He pa sed big time. Using his strength as a big corner, he was able to get his hands on Jones a lot and limit him to three catches for 31 yards. Gunter has had his moments against some receivers this season like Jones and Alshon Jefferey, and he played a big part in limiting Odell Beckham Jr. two weeks ago. But he struggled against the Cowboys, and , giving up a bunch of big plays. It will be interesting to see if this undrafted second-year player will spend a lot of time on Jones again. I think he will, which will make that battle a real focal point of the game. In the first meeting, he got called for a questionable pa s-interference penalty when in a man situation on Jones. But he also made some nice plays. He didn't back down from the challenge. Who the Falcons should attack The Green Bay linebackers have coverage i sues that show up on a regular basis. With the Falcons getting 85 catches from their running backs during the regular season, I would imagine they will pre s the linebackers to cover this week. That means , their best coverage linebacker, and have to be up to the challenge. I don't know if they can be. Those backs are outstanding in the pa sing game. Defensive key They have to get old guys and to show up in the pa s rush. If not, Matt Ryan will kill them. Matthews had five sacks in the regular season, but he mi sed three games, including the first one with the Falcons. He has Tre Norwood Jersey one sack in two playoff games. Peppers had 7 sacks in the regular season and one in the playoffs so far. He had a sack in the first meeting against the Falcons. These two have to get after Ryan -- or else. The Falcons run a lot of long-developing plays, and pre sure can kill those. Young player to watch Outside linebacker : When the Steelers drafted Dupree in the first round in 2015, I thought he'd be the perfect player for their defense, a powerful rusher who could also play the run. He flashed at times as a rookie in his four starts, getting four sacks, but so much more was expected in 2016. But Dupree mi sed the first nine games with an abdominal injury and his absence was felt. Since returning, the Steelers defense is much better. Dupree had 4 sacks in the final five games and has one plus a big hit to cause an interception in the playoffs. His ability to rush Tom Brady will be huge this week. Dupree lost 20 pounds with a no-carbs diet during the offseason, and that shows up now on the field. He is much faster getting to the football. Dupree is also good against the run and chases down a lot of plays in the run game. Last week, he beat right tackle to hit , causing the ball to flutter and enabling to pick it off. He made a few other plays in the run game as well. The Steelers can move him around, sometimes lining him up standing up inside, but he should spend a lot of time working against right tackle . Keep an eye on that one. Who the should attack Free safety is Jack Ham Jersey a big hitter, sometimes too big based on some his shots being flagged. But he isn't great in coverage. I would think that the Patriots will find a way to get him in some bad coverage situations. When the Steelers go to a single-high safety look, it leaves Mitchell in the middle of the field. With him being so aggre sive, Brady will try and use that against him with his eyes -- moving him off the spot to create seams to throw. Defensive key Try to fool Brady. He is outstanding at di secting before the snap, which is why coordinator Keith Butler will be big in this one for the Steelers. They have to give him a lot of looks that will slow him down a tick. "You have to make him think pre-snap," one AFC defensive back said. "If he knows what you are in, you are dead." The Steelers will show a lot of looks, especially up front. They have to confuse Brady and the much-improved offensive line. They aren't good enough on the back end to hold up for an entire game. Young player to watch Defensive end : When the Patriots traded pa s rusher to the before the season, many wondered who would pick up the slack. That guy was Flowers. In his second season, he has emerged as a good pa s rusher, leading the team with seven sacks, all in the final nine games. He didn't get one last week against Houston, but he had a handful of pre sures. At 6-2, 265 pounds, Pat Freiermuth Jersey this 23-year-old will be big this weekend against the Steelers. He will have to win his battles wi
