I used cfbstats.com for this information
Things of note:
-They haven't had any 5 star recruits (Defensively), with the exception of 1 DT who was a FR this year.
-They have gotten maybe 2-3 recruits every year since 2010 who are top 15 in their position, mostly DE's, and some top 5 players from JUCO, some left before he came.
-Has shown improvement, but still not elite in TD's allowed and Rushing Y/G.
-Has gotten slightly worse every year in takeaways.
Edit: Yes, this is all defensive stats, as in Rushing/Passing/Total yards ALLOWED P/G
