Chris Webber is going to bat for Jim Harbaugh ... telling TMZ Sports Michigan should NOT fire the head coach -- this despite his FIFTH STRAIGHT loss to Ohio State on Saturday.
"To throw the baby out with the bathwater or to blow it up just because of that really doesn't make sense," Webber says.
Don't get it twisted ... the Fab Five legend is still pretty pissed over the Wolverines' L -- but he says Harbaugh should get more chances to try to turn the tide.
