They only have a national title ceiling because at one time they each had really good coaching staffs (or in LSU's case, got extremely lucky for one season that they had Joe Brady). That said, without Urban Meyer, Florida is going on 3 decades without a title and is most likely a mediocre team this century outside of a few 10-3 type years. LSU largely has been mediocre-above average for the past 15 years aside from the Burrow year and 2013. Thing is, with the recruiting advantages these schools have, not to mention the complete and total lack of interest the NCAA has in actually investigating anything that happens there, they should never have mediocrity. The reality is, though, they only have a national title ceiling when they have elite coaching, which goes for every team.
