If he is off draft boards, I wouldn't hesitate to get back into the 7th round to draft him. Few 7th rounders ever amount to anything anyway, so I'd not be afraid to take a flier on him. If he's proven innocent, you get a steal of a talent. If he's proven guilty, you shrug your shoulders secure in the knowledge that you invested very little, and you release his rights. No harm, no foul, very little risk.
As for La'el Collins, at the time I was calling for the Colts to call his bluff about refusing to sign & sitting out a year, by taking him in the last round. Again, I figured if you lost out, oh well, no big investment lost.
