For the past few years BTN has done a bus tour traveling to each Big Ten team to watch a practice and provide their opinions on each squad. They don't provide much insight but it at least gives us a first look at the 2014 version of Michigan football. Tour starts tomorrow (8/5) at IU. The show is on BTN daily (called BTN Live) at 6PM EST. They will be in Ann Arbor next Monday, 8/11.
