Former NFL running back Brandon Jacobs spent one season with the San Francisco 49ers in 2012 under head coach Jim Harbaugh.
Jacobs only played in two games and gained seven yards on five carries. The results were nothing like his 5,087 yards and 60 touchdowns over eight years with the Giants.
Apparently being pushed to the bench as a 31-year-old veteran running back didn't sit well with Jacobs.
“Going somewhere where they don’t have route conversions into certain coverages was just absurd,” Jacobs said Thursday on the Tiki and Tierney Show. “They’re just running routes in the defense, getting people killed. Size and strength is what they had, and that’s why they won.
"Let’s be real. They had great assistant coaches, but Jim didn’t know what he was doing. Jim had no idea. Jim is throwing slants into Cover-2 safeties, getting people hurt. That guy knew nothing, man."
On Saturday morning, Harbaugh responded to Jacobs with a tweet to him.

Harbaugh went 44-19-1 in four seasons as the 49ers' head coach. He also added five playoff wins and a trip to the Super Bowl in the 2012-13 season, the one that Jacobs played for him.
