Personally, I don't care much one way or another which logo is the primary and which is the secondary, but I think ANDY! has made some good points here. Just looking at the first page of D1 logos on the mothership, plenty of schools have letter logos, sure, but plenty don't. Would you say that, for example, Arkansas' razorback logo or Boise State's bronco logo or Clemson's tiger paw logo doesn't represent the school? Not innately, sure - to QCS's point, if you showed any of those logos to someone who has never watched college sports, they probably wouldn't be able to identify them - but over time, those marks have become associated with their representative schools. I certainly think Comets is a unique enough nickname that a comet logo would be easily identified as Coastal Florida, especially with a century of history behind it. I can see where you're coming from, though, and I could really go either way, but I think the comet works as a primary more than you're giving it credit for.
