Several things have me thinking about CB recruiting in the '22 class.
First, the impending defensive staff shake up at Michigan. Two names have emerged: Derek Mason and Tim Banks (positive news being this would mean a Harbaugh extension). Things weren't looking great on the Will Johnson front for OSU in the first place (despite the recent visit, the buzz was just checking a box rather than any sort of positive momentum for OSU) and apparently Tim Banks would be a big boost for UM in that recruitment.
Throw in the talk that Will Johnson and Domani Jackson are looking at going to the same school together, and that Domani Jackson's father is a huge UM fan and pushing him there, and things aren't looking so great on those fronts.
Second, Wiltfong just CBed Jaheim Singletary to OSU. And there has been general positive buzz around Denver Harris.
In summary, it looks like the OSU momentum is behind Denver Harris and Jaheim Singletary at the moment and is possibly waining with Will Johnson and possibly Domani Jackson as a side effect. Either way, the defensive staff shakeup will probably help UM in both the latter cases.
You'd take any of these CBs any day of the week and OSU ending up with two out of those four would be amazing.
EDIT: Domani Jackson is still CBed to Ohio State by Kurelic, Loy, and Wiltfong (but with no confidence), so I guess whatever initial positive news they heard might counterbalance the extremely pro UM parental figure. It's a long way to signing day.
