My past four years here at the University of Michigan have been great! Nothing but love and appreciation for Ann Arbor, the faculty, the coaches, the support staff and the great fans but after many sleepless nights and much prayer I have decided to play my final year of eligibility elsewhere. I truly thank those that have been there for me and hope you would continue to do so. #ForeverGoBlue
That is a blow to Michigan's secondary. Countess was the leading candidate to start opposite Jourdan Lewis, give or take a Wayne Lyons, and even in the event he lost the job he figured to see considerable playing time spotting various guys in the secondary.
Countess struggled mightily last year as Michigan transitioned to a man press style, but was an All Big Ten performer as a sophomore in a zone system. It is possible that Michigan apparently rededicating themselves to the aggressive system they had to ditch midseason last year may have precipitated a transfer. Either that or the usual transition stuff compounded by the availability of immediate eligibility elsewhere.
Other than Lyons, the main beneficiaries of Countess's departure figure to be Brandon Watson and Channing Stribling. Watson was impressive in the spring game and has a ton of experience as a press corner; Stribling was promising as a freshman before a relatively anonymous sophomore year.
Countess was set to be a fifth year senior so this doesn't impact recruiting classes going forward; it does end any questions about if any contributing walk-ons would get stiffed. If anyone else leaves Michigan would have a spot to add another fifth year transfer.
Godspeed, Mr. Countess.
