I've seen BT bucks clean of velvet as early as 15 August on cam, which tells me that it rubbed it off prior to that date. I've never seen/read any any stories indicating that the dates they loose their velvet has anything to do with how the seasons will progress.
Every deer is an individual, and will not precisely fit into the mold of what we hunters expect the deer to be doing. For me, I'd just expect that I wouldn't see that deer again until the rut (if it was a BT) ......but that's just me.
