24/7 Sports did an article on recruiting.
15- Michigan- The in-state talent base isn’t terribly deep and Michigan State is a pesky adversary on the in-state talent, but the Wolverines have an established brand, great tradition and facilities and can appeal nationally to prospects. The winged helmets are synonymous with college football (prospects love them) and the “big house” is quite a selling point to elite talent as well. Heisman Trophy winners, championships, great NFL alums- Michigan has it all except ideal geography, which makes it more of a challenging recruiting job than it should be.
Only other B1G programs on the list were tOSU and Penn State. SEC led the way based on geography.
