Bart:
I feel very confident in both the Patriots and Packers winning and also covering the respective point spreads for their games.
1) New England: NFL playoff games are all about which team has the superior quarterback. Tom Brady is far better than Garrard, as we all know. In watching film of Jackonsonville, it is obvious to me that the Jags defensive line will be stymied by the superior offensive line of New England. Jacksonville's secondary does not have the ability to contain the Patriots passing game (Welker, Moss, Stallworth, and even backs such as Faulk coming out of the backfield).
The Patriots defense will force Garrard to beat them. Expect New England to stack the line, with Rodney Harrison making a lot of tackles on the Jags running back duo. Even a quarterback adept at throwing (which we all know Garrard is not) would have trouble completing passes against the Patriots secondary due to the very below average receivers the Jaguars have combined with the cornerback play of Asante Samuel. Ellis Hobbs is a corner who has weaknesses which can be exploited, but Jacksonville does not have the personnel at QB and receiver to successfully attack Hobbs.
I expect the Patriots to win this game by at least 14 points.
2) Green Bay: Matt Hasselback is one of the top QBs in the NFL, yet he has struggled recently and is hurting (thigh and wrist). This warrior will do all he can to lead his team to a win. But, Seattle will fall short. Green Bay has two shutdown corners who are very physical and a league above Seattle's below average receivers. Furthermore, Seattle's running game has been in shambles ever since Steve Hutchinson left. Green Bay's defense is one of the league's best, and is very balanced, with stars at defensive line (Kampman), linebacker (Hawk and Barnett), and defensive back (Woodson, Harris). Seattle's offense will have trouble scoring points.
Offensively, Green Bay's offensive line is superior to Seattle's defensive line (especially with Kerney hurting) and the Packers will be successful in running the football with Ryan Clark. This will in turn, open up the passing game for Brett Favre. As long as Favre plays a smart game, and doesn't attempt foolish passes (as he has done in the past in regular season and playoff games alike) the Packers will easily win this game.
I expect Green Bay to win by at least 10 points.
