Four more coaching vacancies have been filled, or are likely to be filled, today in the NFL with the 49ers, Giants, Buccaneers and Eagles finding their next head coaches.

Here’s a look at what the new coaches will offer to their new teams:

Chip Kelly to the San Francisco 49ers

The 49ers’ offense, which took a nosedive in Jim Harbaugh’s final season got even worse in 2015. Their 14.9 points per game this season was tied for the fourth fewest in a season in franchise history.

Kelly’s up-tempo offense will not be foreign to the 49ers. The Eagles ran a play every 22.7 seconds, fastest in the league. The 49ers ran a play every 26.5 seconds of possession, the fifth-fastest rate in the league.

What’s good for Kelly is that the 49ers have $41.0 million in salary cap space for 2016, the fourth most in the NFL behind the Raiders, Bears and Jaguars (Source: Roster Management System). There is room for him to improve the squad.

Dirk Koetter promoted by the Tampa Bay Buccaneers

In his first season as the Buccaneers’ offensive coordinator, Koetter was tasked with working with rookie quarterback Jameis Winston.

Winston finished just short of the franchise record for single-season passing yards with 4,042 yards passing. Winston became the third rookie in NFL history to pass for over 4,000 yards, joining Cam Newton (2011) and Andrew Luck (2012).

Koetter takes over a team that finished 6-10 in 2015, but will have greater expectations in 2016. The last Buccaneers coach to finish over .500 in his first season as head coach? Jon Gruden, who won the Super Bowl that season (2002).

Ben McAdoo promoted by the New York Giants

Since McAdoo joined the Giants as their offensive coordinator in 2014, the Giants rank top 10 in points, yards per game and Total QBR.

Eli Manning had career highs in touchdown passes (35) and touchdown-to-interception ratio this season (2.5) in his second year under McAdoo.

How? McAdoo made some changes to Manning’s game. Manning cut down his average pass distance from 9.5 yards to 7.9, allowing him to be more accurate.

Doug Pederson likely to be hired by the Philadelphia Eagles

Pederson, the Kansas City Chiefs’ offensive coordinator, cannot officially move until the end of the team's season.

During the 2015 season, the Chiefs ranked in the top 15 in yards per play (12th), yards per rush (3rd), yards per attempt (15th) and Total QBR (7th). The Eagles were in the bottom 10 in each of those categories, including 30th in Total QBR.

Alex Smith finished with a career-high 3,486 pass yards and a 66.5 QBR. Smith went nine straight games without an interception, the longest such streak since Tom Brady went 11 straight in 2010.
