Jim Harbaugh played at Michigan from 1983 to 1986 and finished third in the Heisman Trophy voting as a senior.
Charles Woodson played at Michigan from 1995 to 1997 and won the Heisman Trophy as a junior.
Michigan has a vacancy to fill after firing head coach Brady Hoke last week, and the Raiders will be looking to hire a permanent head coach at season's end.
If Harbaugh doesn't return to the 49ers next year, would the 38-year old safety prefer to see Harbaugh coaching at their alma mater, or in Oakland?
“If the choice was out there, it would definitely be Michigan," Woodson told Rich Eisen of NFL Media. "As a guy that played there, I think the fans would love it, I think it would be great for recruiting and all of that.
"Just to have a guy that’s proven, he’s won everywhere he’s been as a coach and I don’t think it would be any different if he went to Michigan. I would say ‘yeah.’ Go Blue.”
An NFL Network report surfaced Sunday morning saying that Michigan reached out to Harbaugh recently, and left the conversation believing Harbaugh would prefer to remain a NFL head coach.
When CSNBayArea.com asked Harbaugh on Monday if the report was true, Harbaugh responded by saying, "As I've said, as a principle, I don't talk about any other job other than the one that I have."
