I'd say there is a decent chance he will be available at our 3rd/4th. Not guaranteed, but the CB class is so deep, I could easily see teams passing on him. Don't forget last years CB class, while not on the same level as this one, was also decent and 20 CBs went in the first four rounds (5 per round). We weren't the only teams to select CBs last year. 60% of non-Carolina teams selected a CB in the first found rounds last year. Last year and this year was a great opportunity for us to rebuild the secondary with young/cheap solid players.
Anyway, I think even with their injuries, Moreau and Jones could still be picked ahead of him, so him slipping to say CB 15+ is possible and I think that could easily end up being end of the 3rd. He might fall a little more, but I don't see him slipping more than that. There is a definite drop off around there where he would be good enough that you'd ignore the character/speed concerns.
