Well, as it's Oakland County, most of the Judges are extremely conservative. That may change, somewhat, as the Prosecutor was effectively removed from his seat for corruption. . .
If he has a suspended sentence, the Judge can impose that amount of jail time on him. The judge may also expand probation, order more community service. Pretty much, the Judge can do anything they want within the sentencing range.
Hiring a GOOD attorney, especially one who has a relationship with the Judge, may help reduce the punishment. Be sure it's a good attorney, though, Michigan has some of the absolute worst Criminal defense attorneys in the country, due largely to having the worst law school in the country (Cooley) graduating so many people that shouldn't have an undergraduate degree. . . then all the other law schools in the State are awful, except for U of M and Wayne State. . .etc.
As most of those who post here will say, get an attorney. . . and consider getting the hair test.
