I have added an "All-Time Recruit Rankings" (LINK) page to the top. As you might guess, it's a database of every Michigan recruit listed in order of class recruiting ranking. I used 247 Sports' Composite rankings to do the list. It shows, for example, that Jabrill Peppers is Michigan's top overall recruit since 2006, while Justin Feagin is the lowest ranked recruit, though there are several unranked players who are behind Feagin. If you ever have a question about how Michigan's recruiting efforts stack up against historical classes, this should be a helpful resource.
Keep in mind that the page is under construction, but if you have any comments, corrections, suggestions, etc., please leave them in the comments.
