The NFL regular season wrapped up, but that just means plenty of teams are officially kicking off their offseason. And several of the struggling ones are beginning with massive changes up top, specifically at the head coach position.

The Las Vegas Raiders are the latest NFL team with a head coaching vacancy after the franchise fired Antonio Pierce on Tuesday. Pierce only got one season in the official role, and he was plagued with quarterback issues throughout the year. However, he’s now gone, and Las Vegas will work to find his successor.
