NotoriousBRT, the buck limit went from 11 to 3 in 1999. So any improvement you interpret at the current time is a reflection of before they dropped it to 2 for the up coming season. Any "trophys" killed in TN this coming season will have nothing to do with the 2 buck limit.

A changing attitude amongst hunters in general is what has accounted for any improvement in the buck age structure. And by your own account, that was already taking place with a 3 buck limit. The dropping of 1 buck from the state bag limit will just affect less than 3% of the hunting population. That's about all that actually killed 3 to begin with.
