I've watched it. It's well done. I think CBS/Paramount picked these programs to follow based on their likelihood of making a deep run in march.
WRT KU, not a whole lot was new for me, but it was interesting to see some behind the scenes.
The documentary picked a player from each program to shadow and that was Darren P for KU and Yaxle L for Michigan. I felt there was striking contrast between these two players-- Yaxel allowed a great deal of transparency and access to his family, while Darren seemed guarded and less personable, with no reference to his family. There was also some interesting parallels / differences between Self and May. Worth a watch.
Last episode drops April 18. Will feature post-season, which should be a rollicking fun ride for Wolverine fans.
