Ex-49ers RB Jacobs blasts Jim Harbaugh: 'That guy knew nothing'
Bob Stanton / USA TODAY Sports

The widely held belief within the football community is that the San Francisco 49ers' downward spiral came as a direct result of the decision to part with Jim Harbaugh.

And judging by the club's seven total wins in the two seasons since, not to mention the instant success the star head coach has enjoyed in the college ranks at Michigan, it would be difficult to argue that notion.

Unless you're Brandon Jacobs, that is.

The retired running back, who played the 2012 season under Harbaugh in San Francisco, blasted his former coach Thursday on CBS Sports Radio's "Tiki and Tierney."

"Jim, I had a lot of respect for Jim when I was there - before I got to know him," Jacobs said. "I enjoyed my time there, but we didn't see eye to eye. I knew a little bit more about football than what they led on."

Going into specifics about what he recalls about Harbaugh's offensive system, including certain route concepts, Jacobs suggested the scheme wasn't exactly sophisticated.

"Going somewhere where they don't have route conversions into certain coverages was just absurd," said Jacobs. "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."

Jacobs was a non-factor during his lone season with the 49ers, limited to just two games and seven yards on five carries.

Now a social media savant, and clearly not afraid to clap back at those who call him out, perhaps we should all be staying tuned for Harbaugh's response.
