When you invest as much money as Louisiana does into coaching and support staffs, two things are absolute.

You're going to lose players because you have better players than the rest of the G5.
You're going to lose support staff because your support staff dwarfs most of the G5.

So, yeah, Louisiana lost a LOT of support staff, because they had a lot of staff to lose.
Louisiana lost good players to the portal because they have more P5 level players, thanks to the commitment made to this program.

This isn't brain surgery guys.
