The Oakland Raiders announced Monday that they fired offensive coordinator Greg Knapp, special teams coordinator Steve Hoffman, offensive line coach Frank Pollack and linebackers coach Johnny Holland.
"Decisions like this are very difficult," first-year coach Dennis Allen said in a statement. "I have a great deal of respect for all of these men and I appreciate their contributions to the Oakland Raiders this season."
Oakland finished 18th in total offense this season at 344 yards per game, but the Raiders ranked 28th in rushing with 88.8 yards per game. The lack of a ground attack contributed to the team frequently falling behind, which in turn led to increasing passing stats as the Raiders played catch-up. Oakland ranked eighth with 255.2 passing yards per game, although the team's average of 6.9 yards per completion tied for 19th.
Knapp was the Raiders' offensive coordinator in 2007-08. He also held the same post with the San Francisco 49ers (2001-03), the Atlanta Falcons (2004-06) and the Seattle Seahawks (2009). He served as the Houston Texans' quarterbacks coach in 2010-11.
The Raiders finished the season 4-12 under Allen. They will get the third, fourth or fifth pick in the 2013 draft.
