I love Bowl Games. Always have and always will. However, something does need to change to kick it up a notch for the non-Playoff Bowls. The NY6 Bowls will be stronger than ever as part of the 12 Team Playoff.
As for the rest, I like several ideas already expressed with a little lemon twist:
I would have a few of the select historical Bowls like the Citrus, Sun, Gator, Liberty, Holiday, ReliaQuest, etc. have a day to themselves on or near NYE / NYD depending on how the Playoff schedule is staggered with Winner and Loser pay.
Then, with the other P4 Bowls like the Alamo, Las Vegas, Houston, Music City, Pop Tarts, Guaranteed Rate, etc. use Week 0 for some of them as an extra game not counting against the 13 game schedule for the 4 Power Conference teams. Let the host P4 Bowls choose who they want like the old Kickoff Classic, Pigskin Classic, etc. with Winner and Loser pay.
Finally, some of the Bowls that want to match-up Champions and other teams for the G5 Conferences like the Birmingham, Camellia, Mobile, Bahamas, Military, Frisco, Arizona, etc. etc. can be staggered through the Holiday season, as most of those teams will not have serious opt out issues with Winner and Loser pay.
It's a fluid working plan!
