A spike in AL is not an indication of anything that he can or can’t do at maturity.
A few years ago I passed on what I believe to be a 2yr old spike. The spikes were about a foot tall and the one on his right side has a sharp bend about half way up. 2 years later, my buddy shoots one afternoon and tells me he shot a big bodied tall 6pt. I went meet him and when I walked up to the deer, I immediately notice the right antler had a sharp bend in it about half way up. The antlers we probably 15-16” tall and only had about a 10-12” spread with big forks and small brow tines. Till this day I believe that was the exact spike I let walk 2yrs prior. He wasn’t a monster but my buddy was dang proud of him and I sure would have been happy to kill him. You never know what a bucks potential is if you kill him when he’s a baby.
