It perpetuates the fallacy that Harbaugh inherited a team with no talent - they had top 10 recruiting classes every year
I love to hate on Harbaugh just as much as the next guy, but this isn't entirely true. 2012 and 2013 were top 10 classes, but 2014 and 2015 (the two classes prior to Harbaugh taking over) were 20th and 37th respectively. There was plenty of talent, but not Ohio State/Alabama/Clemson levels of talent waiting for Harbaugh upon his arrival. That 2013 class just graduated, so now we get to see how well he does with 2 mediocre classes (by Michigan standards) and then his own recruits.
