Why do some want a 2 buck limit? The only difference it will make is on wma's because many of those who own land and hunt (not all) will shot as many as they want. I personally only normally kill 2 a year and rarely kill a third but it's nice to have that in my pocket during late season.
Exactly people who will shoot 2 off the top because they've a 3rd tag would stop them from shooting that 2nd immature buck....
That is completely speculative. People who shoot "immature" bucks do so because they want to and because they don;t care about antlers and just want the meat. They also know you get as much meat off a 1.5 yr old buck as a 3 yr old doe and it doesn't taste any worse.
If they pass and wait for a doe, that opportunity may not come, but this one is here right now, so it pays to take the deer and not take the risk of not seeing a doe. Keep in mind not everyone has high deer densities where they hunt, even in Mid TN.
The guys like you that care about horns won't shoot the first immature buck so it comes down to choice and they should have that choice whether you agree or not.
I hunted Rutherford and Wilson counties this year. I saw lots of spikes and small bucks. I think I saw 10 does total from the stand from the bow opener to the last day. those 10 were seen on 3 separate sits in groups of 3, 4, and 3.
