I know Scott and think he's genuinely an honest and good guy. That said, you simply can't make statements like that on 2.5 yr old bucks and be accurate. Heck, it's hard to make generalizations on antler sizes at 4.5+. At 2.5, soooooooooooooo much of what a buck has on his head is still dependent on its birth timing. I think it was John Ozoga (I know it was someone I take seriously) that said it takes a late born buck to get to be 3.5 before he really starts to shake off the impact of being born late, as it is revealed in his rack, if he is ever able to do so. My experiences line up perfectly, with that.
I've managed some absolutely primo grounds in what I feel is the ideal latitude belt (far enough south so the deer aren't really winter stressed, but far enough north that they are still a large enough sub species...Think N MO, IA, IL, OH, KS). I've never had the "majority of 2.5 year old bucks in his (any) area would meet(ing) the P&Y minimum" anywhere. I also managed a big chunk of SE MN for a good stretch of time, and I'm talking primo SE MN ground...didn't see that there, either.
I should clarify something I wrote earlier, though...I see plenty of bucks get called older than they really are in MN, WI & MI. The catch is that we don't have as many 2.5s and 3.5s that sprout incredible antlers for their age as one does in the N MO, IA, IL, OH, KSes of the world. Most hunters try to gauge age on rack size. When dealing with the 110" 4.5 yr old I had in C MN last year, most tend to think "oh, in one more year he'll be a good one, as he has to be young to have 110 inches." The 160" 12 point in IL a couple years ago, hunters tend to naturally believe he has to be a mature buck, as only mature bucks have racks like that.
There was a thread over on QDMA this past winter where they showed 4 bucks (kill and trail cam images) and asked for age guesses...3 of the 4 were 2.5 or 3.5, but most everyone over guessed their ages, as having racks that big must mean they are older deer.
