I am wondering if it's this guy… only had 1 pic of him from mid June-Jan when season closed and I pulled my cameras…
Not the same buck, imo.
"This guy" (last year) appeared significantly wider and taller than the velvet buck in your 1st pic, albeit the velvet buck isn't half done growing yet.
Also, note the velvet buck is growing a much longer (relative to R-G2) R-G3.
The more common antler configuration is for the G2s to be longer than the G3s.
That guy from last year appeared to have near equal, but still slightly longer G2 than G3 on his right antler.
Usually, with velvet bucks, the antler tines closest to the head grow & finish growing first.
Note on the velvet buck that his R-G3, despite beginning to grow later, is already significantly longer than his R-G2. This single difference between "this guy" and this velvet buck is a near certain indicator we're looking at different bucks.
I believe there will soon be some other significant antler differences that rule out these being the same buck. These include main beam configuration & curvature, as well as width. Another biggie will be differences of each buck's G1's.
