Couple thoughts.
1) B1G bowls have less say in what B1G team they choose. Delaney wanted more input (and got it) because teams were headed to the same place, against the same team, too frequently.
2) Iowa's AD was on his knees and begged to get into the Outback Bowl.
3) Iowa played Tennessee 2 years ago, it was ugly. Iowa begged not to be there and Delaney didn't want a rematch in a bowl (and had the power to do something). Pretty simple.
4) If you're a single guy in your 20's grab your buddies and get your ass to Nashville. So many women. You won't regret it. Easy road trip.
5) If you're an old married guy, like me, take your wife, grab your friends, it's a great place for a weekend.
6) Yeah, I'd like to be 13-0 and headed to be Peach Bowl too. But, this season showed a lot of progress, there's a shot for 10 wins, and we're playing a super talented SEC team. Rocky Top on their turf. This looks like a hell of a trip.
