Saints, LSU or both
I am an NFL fan first and foremost and over college by about 9:1. I believe rooting for your local team is noble. That makes me a Saints fan first and I post here more than any other sports forum. MOST of my follows on Twitter are Saints folks and it is really the only reason I am on Twitter.
For college, I believe supporting your alma mater as primary is NOT optional.
I went to Louisiana Tech.
I grew up in a die hard LSU household. I had a distant relative who was briefly chancellor.
I am currently employed by Tulane.
I have strong affinities for LaTech and Tulane due to the communities I developed there. I root for LSU because it makes my friends and family happy.
I have noticed over the years that when LSU is competing for national titles, the other in state schools actually perform fairly well. Louisiana Tech's bowl win streak (2014-2020) coincided with LSU being a national champion. I see no discomfort in rooting for all the state schools until they play each other and I tend to root for outcomes that have a positive net impact on the state ...
My rooting order in college is
Alma mater over any other school
In State vs out of state
Smaller teams over larger teams
Region / Conference over the rest of the country
I do root for schools friends and family go to.
Of the lower levels of football, I prefer high school football -- likely because my son is playing right now.
