Denver Broncos

New faces: WR Wes Welker, G Louis Vasquez, DE Shaun Phillips, DT Terrance Knighton, CB Dominique Rodgers-Cromartie.

Saying goodbye: RB Willis McGahee, WR Brandon Stokley, C Dan Koppen, DE Elvis Dumervil, DE D.J. Williams.

Youth movement: Veteran back McGahee, the former Bill, was replaced by Wisconsin touchdown machine Montee Ball.

Best young player: WR Demaryius Thomas, right.

Pressure’s on: LB Nate Irving. He has the monumental task of filling in for the suspended Von Miller for the first six games of the season. He won’t provide the same level of production, obviously, but Irving will be counted on to provide adequate play in Miller’s absence.

Kansas City Chiefs

New faces: QB Alex Smith, WR Donnie Avery, TE Anthony Fasano, G Geoff Schwartz, DE/DT Mike Devito.

Saying goodbye: QB Matt Cassel, RB Peyton Hillis, TE Kevin Boss, OT Eric Winston, DT Glenn Dorsey.

Youth movement: The Chiefs added to a young, talented offensive line by taking Eric Fisher first overall in April’s draft.

Best young player: LB Justin Houston: The third-year pro was one of six Pro Bowlers on a team that went 2-14 last season. That in itself is amazing.

Pressure’s on: DT Dontari Poe. The 11th overall pick in the 2012 draft started all 16 games as a rookie, but barely made an impact with 38 tackles and no sacks. The Chiefs need more for their investment.

San Diego Chargers

New faces: LT King Dunlap, LT Max Starks, OLB Dwight Freeney, ILB Manti Te’o, RB Danny Woodhead.

Saying goodbye: CB Quentin Jammer, OLB Shaun Phillips, RG Louis Vasquez, LB Takeo Spikes, SS Atari Bigby.

Youth movement: It happened in the front office, where 40-year-old St. Francis graduate Tom Telesco took over as general manager.

Best young player: DE Corey Liuget. The third-year defensive end had seven sacks and 51 tackles as a 3-4 defensive end last season. He also broke up nine passes.

Pressure’s on: LT King Dunlap. The free agent signee looks to be the favorite to win the job protecting Philip Rivers’ blind side. As such, he’ll have a big responsibility in keeping Rivers — who was sacked 49 times last year — on his feet.

Oakland Raiders

New faces: QB Matt Flynn, DB Charles Woodson, CB Tracy Porter, LT Alex Barron, DT Pat Sims.

Saying goodbye: QB Carson Palmer, DT Richard Seymour, DT Tommy Kelly, DE Matt Shaughnessy, LB Rolando McClain.

Youth movement: Terrelle Pryor has won the starting quarterback job over veteran Matt Flynn. Pryor’s got speed, which he’ll need, because he’ll be running for his life.

Best young player: DE Lamarr Houston. The pickings are slim on a roster that desperately needs upgrading, but Houston had a solid season in 2012, with 69 tackles and four sacks.

Pressure’s on: GM Reggie McKenzie. The Raiders have an incredible 40 percent of their salary cap committed to players who no longer on the team. That’s quite a hole to dig out of. — J.S.
