Michigan Wolverines football has begun fall camp, and expectations are as high as ever in Ann Arbor. The Maize and Blue are shooting for their first national title since 1997, and plenty has to go right for them to capture it. ESPN.com college football writer and analytics guru Bill Connelly put together his annual 'ifs list,' an attempt to see how many 'ifs' it takes to turn a team into a "genuine national title contender." Georgia only had two, while Michigan, Alabama, Georgia, LSU, Penn State and Tennessee made up the group with three. Let's break down Connelly's three 'ifs' for Michigan, which are essentially three question marks we've been discussing about this team all offseason.
