Hiring away Wisconsin's WR coach/passing game coordinator.
No official position announced, but rumored to be TE coach. You probably unintentionally absorb more TE coaching knowledge coaching WRs at Wisconsin than you do actually coaching TEs anywhere else.
And Harlon Barnett, who left to be be DC at FSU, is back as DBs coach, as he was under Dantonio, first at Cincinnati, then at MSU, from 2004-2017. We had some pretty good secondaries in there.
So it seems like we retained our DL coach, retained our DC as LB coach, brought back our pre-2018 DB coach, and completely flipped the offensive staff. Basically a best realistic case scenario from a staffing standpoint.
