One of the big reasons that the Seahawks were able to beat the Washington Redskins was the fact that the Redskins receivers were intimidated. Early in the game the Skins receivers were able to make some plays but as the game went on, the Seahawks played a physical in-your-face style of defense and it affected the outcome. The Redskins receivers started to drop passes and got taken out of their game and all the momentum swung to the Seahawks.
That's not going to happen against the Falcons. The Falcons have the best one-two punch in the NFL in Roddy White and Julio Jones and both are very tough receivers that are more than willing to go over the middle and will hold their own against physical defensive backs. White proves his toughness game-in and game-out and is one of the true gamers in the league. Jones is a physical freak of nature and hasn't been known to back down in his college or brief pro career. Add to those guys, one of (if not the) the greatest tight ends in NFL history and you have a core group of receivers that aren't going to be affected when the Seahawks try to play a physical brand of football with the Falcons receivers.
In fact, I would look for the Falcons to go after Brandon Browner from the get go. Early in the game, the Redskins had success going after Browner but seemed to go away from it as their receivers folded. The Falcons receivers should also have more time to get open as the Seahawks Chris Clemons suffered an unfortunate season ending injury against the Redskins. If the match-up between the Seahwaks secondary and the Falcons receivers is an advantage for anybody, it will be an advantage for the Falcons.
