Well it certainly took guts to play Indiana in 2009 and 2010. It's great that UK schedules a number of games with traditionally strong programs, but to argue that UK's schedule is tougher because it would include UCLA or North Carolina while Duke was playing Ohio State in the B1G Ten ACC challenge, is simply an absurd argument to make.
Duke knows they will get a big name team in an event like the B1G-ACC so they build their schedule around that.
