What's appealing about watching LSU beat up on Georgia Southern, Northwestern State, and Utah State? Because those were the out of conference games they played this year. Alabama played a similar OOC schedule. Meanwhile, Clemson played Texas A&M, Charlotte, Wofford, and South Carolina but they also played an ACC schedule that was filled with a bunch of bad teams.
Point is...regular season schedules aren't the same and they are, by necessity, created years prior to the season so there really isn't a good way to ensure that the schedule for one team is like the schedule for another. So, given that schedules aren't equal, then regular season scheduling and "this team has a loss so it's a shame they got in"...which is the argument you are making...is a faulty argument.
It's very simple. I like seeing meaningful college football games. So if it means UGA gets a shot as a one-loss team sometimes, so be it. Give me the "top 8" teams and let's let them play it off to see who wins. I'll take that over more patsy out-of-conference regular season games all day long.
