Since the start of the NFL New Year the Oakland Raiders have been busy, adding depth and competition on both sides of the football.
However, they haven't been the only team that's been busy, as the other teams in the division have been active in free agency as well.
It hasn't even been a week since the onset of free agency, but the AFC West already looks drastically different than it did at the end of last season, so let's give you a quick update of what's happening around the rest of the division.
After an impressive 18-year career, punctuated by a win in Super Bowl 50, Peyton Manning officially retired from the NFL last week in an emotionally-charged speech at the Paul D. Bowlen Memorial Broncos Centre in Englewood, Colo.
As memorable as Manning's speech was, it was what happened afterward that was truly pertinent for the rest of the AFC West.
Manning's departure in Denver meant that the Broncos were in search of some consistency at quarterback, but after the team made a contract offer to Brock Osweiler – an offer he perceived to be unsatisfactory – the former Arizona State Sun Devil elected to sign with the Houston Texans.
John Elway and the Broncos didn't waste any time finding a replacement for Osweiler, as they traded for veteran signal caller Mark Sanchez Friday.
However, it remains unclear if the team is set to move forward with Sanchez as their starter, or if they'll bring in another quarterback to challenge him.
The team has been linked to current San Francisco 49er Colin Kaepernick and could also look to the draft for even more depth.
KANSAS CITY CHIEFS
When free agency officially kicked off last week, the Kansas City Chiefs didn't waste any time in re-signing one of their top targets, their own linebacker Tamba Hali.
General Manager John Dorsey said that Hali was, "one of the most passionate and competitive football players," he'd ever been around, and during his ten years in Kansas City, the veteran linebacker has been incredibly productive, totaling 582 tackles, 81 tackles for loss, 149 quarterback pressures, two interceptions and 86 sacks.
The Chiefs weren't done making splashes yet though, as they also bolstered their offensive line by signing offensive tackle Mitchell Schwartz.
In addition to Hali and Schwartz, the Chiefs also retained Jaye Howard, Frank Zombo, and added David King, Jonathan Massaquoi, Efe Obada, and Rod Streater.
SAN DIEGO CHARGERS
The Silver and Black added depth to their secondary by signing cornerback Sean Smith from the Kansas City Chiefs, and the San Diego Chargers did the same, bringing in Casey Hayward from the Green Bay Packers on a three-year deal.
In his career, Hayward has appeared in 51 games, totaling 168 tackles, 35 passes defensed, nine interceptions and one pick-six.
The Bolts also added pieces on the offensive side of the ball, giving Philip Rivers another weapon by signing wide receiver Travis Benjamin.
Benjamin enjoyed a career year in 2015 with the Cleveland Browns, hauling in 68 catches for 966 receiving yards and five touchdowns.
*On a related note, former Chargers safety Eric Weddle announced Monday that he would be signing with the Baltimore Ravens.
