Nobody says they’re perfect but there’s a reason bama, OSU, Clemson, Georgia, etc... are competing for championships and are consistently in the top 10 in the recruiting rankings.
It’s a chicken or the egg scenario. Those programs bring in the best classes because guys that get commitable offers from those programs get higher ratings than those for other programs. Also, those programs bring in more 5* players than anyone else, and those are the guys that are easiest to rate because everyone knows they are good already. Most of the guesswork is which 3* and even most 4* guys are going to pop vs. which ones are going to bust. Nobody has figured that one out yet.
As it relates to the original topic of UT recruiting, just putting the composite class rank isn’t nearly enough data to judge whether or not the “cupbooard is bare”. The better way is to put together a list of every 4* and 5* player from those classes (bc those are the guys that are making the rankings that high). Then ask the following questions:
How many are still there?
What are each of their accolades (years lettered, All-SEC, NFL draft picks or projected draft picks)?
How many are currently listed #1 on the depth chart?
Who is there but injured?
What positions do they play?
I don’t care enough about it to do all that research, but if you really want to answer the question that is the level of detail that is needed.
