Most overrated coaches imo are Brian Kelly, Kirk Ferentz & Jim Harbaugh.
Most underrated coaches: Gary Patterson, David Shaw & Paul Chryst.
Gary Patteson is one of the top 3-5 coaches in college football imo.
People may not like him but James Franklin is a pretty **** good coach. He actually won 9 games back to back at Vanderbilt, you know how hard that is to do at Vandy? He even beat Richt in 2013, he deserves respect for what he's done thus far.
Also, people sleep on David Shaw because they say Harbaugh created the foundation, but Harbaugh hasn't been at Stanford since 2011 & he was only 29-21 there, so it's not like Shaw is winning with a bunch of Harbaugh recruits. Shaw is 73-22 since becoming HC & has won 3 Pac-12 titles while putting multiple great players in the NFL despite handing out the least amount of offers of any D1 program.
Maybe people forgot, but Stanford wasn't built by Harbaugh, they were a viable program during the Bill Walsh era & came back on the scene during the Tyrone Willingham era, Harbaugh does deserve credit for his 3 years there no doubt, but he gets a little too much credit.
