Does anybody know for sure how many commits/signees LSU takes in this class?

Or is it debatable? Are they leaving some room for guys that didn't qualify for last year, or do they still count them for last years class? I've never fully understood, well been curious, until now. I'm looking seeing some really good commitments this year and last year, but I'm worried about DT. If we only get 1 DT signee in 2 years, we're going to be desperate! I would hate playing parts of our schedule with walk-on's.
