Not a bad pick, honestly.
At first, I thought the ReliaQuest Bowl was some trash-tier toilet bowl, but it's actually the old Outback Bowl. Historically, the Outback Bowl had the 3rd pick of available B1G + SEC Teams after the BCS Bowls were filled. The current arrangement is a bit less strict, but Athlon is projecting Ohio State, Michigan, Penn State, and Oregon to make the new CFB Playoff Bracket, which infers that they view Nebraska as the best "non-playoff" B1G Team available.
Again, this is just a prediction, but it means they think NU is probably a solid bowl contender. In that tier of B1G teams going to "good-but-not-elite" bowls, they also are forecasting USC (Alamo), Iowa (Citrus), and Washington (Holiday).
Gut reaction? It's nice to be considered in that B-Tier of B1G teams making solid bowl games again. Not where we want to be long-term, obviously, but a far cry better than (a) not making a bowl, or (b) making some Cactus Bowl against the 9th-best MAC Team.
