If Conley is 100% certain of his innocence then he should seriously consider withdrawing his name from the draft.
There is not enough time to change the public opinion that would allow a team to draft him in the first round. He may convince some GM's and owners but the public hasn't been convinced of his innocence.
So, sit out a year... ensure that charges are never filed, are dropped, or you prevail in court. Come back next year and you'll still be one of the top corners in the draft, if not THE top corner since there are 6 highly regarded corners this year.
If he goes in the first round next year he'd basically save himself $9.5M from going undrafted and signing as a free agent in a couple months when all this is rectified.
GM's are saying that he had a spotless background. I'm going with innocent until proven guilty on this one.
