Apparently the network is running this new show during the season to follow a handful of players trying to make a roster. They just showed a ~10 minute clip of Unga - lots of BYU facilities shots (LES, weight room, etc.) and BYU references as Unga tells his story.
Looks like they'll be following him and chronicling his efforts. I believe they said Undrafted premiers on October 23.
I'm definitely interested in watching this - hopefully he can find some sustained success and really make it at this level.
