I'm not sure that even then that they could coast. The lower seeds get better every year. For example, here are the current 8/9 seeds from one bracketologist: 8's: Oregon, Kentucky, Butler, Villanova 9's: Air Force, Georgia Tech, Xavier, Indiana Those aren't easy teams to get by in the 2nd round. Wisconsin still would have a good chance of getting to the Sweet 16, but certainly not coasting. Obviously who those teams are in the 8/9 slot are going to change over the next week, but the same quality of teams will likely still be there.
