Not sure where you have Hendo's stock pegged but I think its perfectly appropriate to have him in the 10-15 range where he lands on most media outlet's draft boards. In the 6-9 range I'd have a hard time passing on him, but that's probably a pretty hot take.
I'd think his range is realistically 8 - 16. Workouts and interviews will mean a lot, but he fits in just about anywhere.
