1. Tony Romo — The Cowboys use a platoon system at quarterback, alternating between Dr. Henry Jekyll and Mr. Edward Hyde. Jekyll gets more playing time, but Hyde often makes appearances in big games. Sunday's Dallas-Philadelphia game is an important one, with first place in the NFC East at stake. Jekyll, who also goes by the pseudonym "Tony Romo," has been on his best behavior lately, with 918 passing yards, eight touchdowns and zero interceptions in his last three games, all of them Dallas victories. The Cowboys split their two games with the Eagles last season, with Jekyll throwing for 312 yards and three TDs in the first meeting, a 41-37 win for Dallas, and Hyde completing 21-of-39 passes, throwing an interception, losing two fumbles and taking three sacks in a 44-6 Dallas loss in Week 17. Budding superstar Miles Austin is said to prefer playing with Jekyll, but Hyde has been petitioning head coach Wade Phillips for playing time. The choice of starter for Week Nine is said to be a game-time decision.

2. Chris Johnson — The Titans got another superhuman performance from Johnson last week. His 228 rushing yards and two TDs against Jacksonville helped give Tennessee its first win of the season, and he embarrassed the Jaguars with an 89-yard TD run in the fourth quarter. (Let's just say the footage of that play won't be used for any "How to Tackle" instructional videos.) It's hard to believe that it was only Johnson's second-best game this season, and equally hard to believe that the 89-yarder was his second-longest TD run. Johnson had 284 rushing-receiving yards and three TDs in a Week Two loss to the Texans, with a 91-yard scoring dash. The Titans visit San Francisco this week, and unlike the Jaguars, the 49ers have some tacklers (star LB Patrick Willis among them) who know how to wrap up. The Niners rank second in the league against the run, allowing 84.9 rushing yards per game.

3. Reggie Wayne — When you watch this master craftsman ply his trade, it's almost inconceivable that he was considered something of a disappointment early in his career. Wayne was a first-round draft pick in 2001 but didn't become a full-time starter for the Colts until 2003, and he didn't have a 1,000 season until 2004. Now, he's working on a sixth consecutive 1,000-yard season and is on pace to record career highs in catches, receiving yardage and TDs. But Wayne's excellence goes beyond the numbers. To watch him is to appreciate just how brilliant he has become. Wayne has neither exceptional size nor track speed, but he knows every nuance of his position, and it seems as if he and QB Peyton Manning have some sort of supernatural telepathy between them. The Colts host the Texans this week, so Wayne will get to compare his skills to those of Andre Johnson in a game that should add new fuel to those best-receiver-in-the-league debates. And here's another debate worth having: When Manning's career is over, who will be considered the best receiver he ever played with - Wayne or Marvin Harrison?
