The Final Four may be predictable, but the remaining outcomes are still unpredictable. Here is my take on the two conference championship games:

NFC: Tampa Bay at Philadelphia -- Sunday, 3 p.m. ET
The Eagles look like they have everything going for them. Donovan McNabb is back. Duce Staley is running well. Their defense is performing at a high level, with terrific cornerbacks in Bobby Taylor and Troy Vincent. They have the NFL's best kicker, David Akers, and one of the league's best return men in Brian Mitchell. Combining every area -- offense, defense and special teams -- Philadelphia is the best team.

Philadelphia is trying to follow the same pattern Green Bay once did. The Packers advanced to the divisional playoffs in 1994, to the NFC title game in 1995 and to the Super Bowl in 1996, when they beat New England. The Eagles made it to the divisional playoffs in 2000, to the NFC title game a year ago and are trying to advance to their first Super Bowl since 1980. Eagles head coach Andy Reid was on Mike Holmgren's staff when the Packers won the Super Bowl and runs the same style of offense.

On the other side, Tampa Bay has the NFL's No. 1 defense and an offense that is nothing spectacular, except for head coach Jon Gruden's creative play-calling and the 7,000 plays he will have prepared for the game. The Bucs receivers are big, but not fast. The running game is only decent, but not outstanding. And their offensive line is the team's Achilles' heel.

While I don't take anything away from Tampa Bay's offensive prowess last week against San Francisco's defense, which wound up having safeties covering wide receivers, Tampa Bay's defense and Brad Johnson's passing efficiency will make for a close, low-scoring game. I'd be surprised if either team scores in the 20s.

Under Gruden, Tampa's offense is much more diverse and efficient than it was when the Bucs lost to the Eagles the last two years in the playoffs, without scoring a touchdown. When the Bucs and Eagles met in Week 7, Gruden was still trying to figure out what he had offensively. Meanwhile, the Eagles' Donovan McNabb was 100 percent and playing like the league MVP.

On Sunday, McNabb has to run the ball for the Eagles' offense to be effective. But the Bucs have dealt with his kind of mobility before. When they switched divisions this season, the Bucs' defense moved into one with Michael Vick and Aaron Brooks. Dealing with mobile quarterbacks have become a priority for the Bucs.

As for this being the last NFL game at Veterans Stadium, thank God. I remember playing in Philadelphia one year, and I ran into the Redskins' mascot, the Indian, a week later with a broken arm. The Eagles' fans at the Vet had thrown him out of the stands. There is probably a bigger chance of there being hostility in the stands than there is on the field.

To understand the importance of home field, look back at last week. All four home teams won. I don't care if it's the Vet, Raymond James Stadium or the USS Kennedy; everybody wants to play on their home field because it is such an advantage. Plus, the Eagles will be playing on turf, a surface that is comfortable for them.

Key matchup: The Bucs' offensive line vs. the Eagles' front seven. If the Bucs have a problem on offense, it has been their offensive line's ability to block. And Brad Johnson isn't going to run away from anybody.

AFC: Tennessee at Oakland -- Sunday, 6:30 p.m. ET
The Titans have a chance to take a look at what they did in the Week 4 loss to Oakland (52-24) and learn from the experience. Everything went wrong for Tennessee. But the Raiders' offense puts a lot of pressure on other team's offenses not to make mistakes. If a team gives the Raiders a short field, they will capitalize.

Eddie George's health and his fumbling are concerns for the Titans. Not only did he suffer a concussion, but he fumbled twice. George runs upright and gets hit a lot. And like the Bucs will be playing in a nasty stadium like the Vet, the Titans will be playing a nasty group of players, led by linebacker Bill Romanowski. The Raiders also have one of the smartest defensive players in Rod Woodson. He doesn't have interceptions because they fell in his lap. He is in position to make plays. And Charles Woodson gives their defense a lot of swagger.

The responsibility of this game falls on the Titans' ability to keep pace with the Raiders, and Oakland has the most complete offense in football. The Raiders have the best quarterback (Rich Gannon), one of the top running backs (Charlie Garner) and the most efficient receiving corps that includes the threat of Jerry Porter. Oakland has to feel like it can move the ball against the Titans. In contrast to Tampa Bay's offensive line being a liability, the Raiders might have the best offensive line in football.

Tennessee's challenge will be for its wide receivers to make plays against the Raiders' defensive backs. For everything he accomplished, Jets quarterback Chad Pennington really got out of whack last week. Can Steve McNair come up with the key third downs running the football as he has in the playoffs? No team is more reliant on one player more than the Titans are on McNair. If the Titans go back to the Super Bowl, it will be because of McNair. So far he's the MVP of the playoffs.

This game will be difficult for Tennessee to win. So how can the Titans win? They can if the Raiders do what they did during their four-game losing streak -- fail to make plays in the passing game. If the Oakland receivers drop five passes, Tennessee will win.

Key matchup: McNair vs. Oakland's defense. The more first downs McNair can convert, the longer he can keep Oakland's offense off the field.
