Michigan has hired former 49ers/UCLA offensive coordinator Michael Johnson in some capacity:

Michigan has all nine of their assistant coach spots filled so Johnson is an analyst until such time as the NCAA approves a tenth assistant coach, which is expected to happen in the near future. Sam issued a gut feeling that a guy matching Johnson's description would be coming in to help coach the WRs, which he's done on and off in the NFL.

Johnson's son, Michael Johnson Jr, happens to be 247's #1 dual-threat QB in the 2019 class. Johnson was until recently his son's coach. This is either good or bad for Michigan's chances with him depending on how this "individual associated with a prospect" legislation works out and what role Johnson actually fills.

If Johnson is the tenth assistant then Michigan can definitely recruit his son because the legislation only applies to non-coaching jobs. If he's a staffer, the legislation stipulates that you can't hire a guy for a two year period before the prospect's projected enrollment. Johnson Jr is more than two years from enrolling, so Michigan might be fine. There is some disagreement about this from our law-talking guy.

FWIW, Johnson was Jim Harbaugh's QB coach for a brief period when both were with the Chargers.
