Tom Brady, QB, New England Patriots

Brady is entering his 18th season in the NFL and is fresh off another Super Bowl victory. One of the league's all-time greats, Brady had 466 yards passing in New England's epic comeback against Atlanta to win the Lombardi Trophy. The only question is how long he can keep it up. Brady just turned 40.

Jake Butt, TE, Denver Broncos

Butt tore his ACL in Michigan's Orange Bowl loss to Florida State and slid down draft boards. The Broncos grabbed him in the fifth round. Butt will start the season on the PUP list, meaning he'd be eligible to return to the field after six weeks. Denver expects him to play this season.

Frank Clark, DE, Seattle Seahawks

When Clark isn't starting fights with teammates, he's been productive for Seattle. Clark had 10 sacks last season for the Seahawks, his second in the NFL. He injured his wrist in the third preseason game, but is expected to be ready for a Week 1 game against Green Bay.

Amar Darboh, WR, Seattle Seahawks

The third-round pick had a very quiet preseason. Darboh didn't catch any passes the first three exhibition games, and then had three grabs in the finale. If not for his draft status, Darboh might have ended up on the wrong end of the roster bubble.

Devin Funchess, WR, Carolina Panthers

Funchess is entering his third season with the Panthers, and the pressure will be on him to produce. He's expected to start opposite Kelvin Benjamin, but Carolina also has tight end Greg Olsen and added weapons Christian McCaffery and Curtis Samuel in the draft. Funchess had 23 receptions last season.

Ben Gedeon, LB, Minnesota Vikings

Gedeon was drafted in the fourth round for the Vikings in April and has shined in the preseason. He'll certainly be on the field in Week 1, and could even start at middle linebacker.

David Harris, LB, New England Patriots

Harris is in his first season wit the Patriots after spending his entire career with the New York Jets. Over 10 seasons in New York, Harris racked up 1,260 career tackles and missed just one game the past eight seasons. It remains to be seen how big his role is in Bill Belichick's defense.

Chad Henne, QB, Jacksonville Jaguars

Henne was given an opportunity to win the starting job away from Blake Bortles, but will still serve as his backup, at least for now. Henne started the third preseason game, but the Jaguars are going with Bortles for Week 1. Henne is entering his 10th NFL season and has started 53 games in his career.

Jabrill Peppers, DB, Cleveland Browns

Jake Rudock, QB, Detroit Lions

The former sixth-round pick has elevated himself to Matthew Stafford's backup in Detroit, and has played well in the preseason, enough that other NFL GMs might be interested in him for a larger role. The Lions, of course, hope he never takes a regular-season snap in 2017, after just signing Stafford to the richest deal in NFL history.
