Like everything else things get over-rated
Tree sands of course never fit every location. Like west Texas.
But many inexperienced hunters wouldn't always know when to use a stand; when not use a stand. Some just follow the herd, wherever that takes them.
Close in during archery means the deer has a better chance of scenting you on the ground, than you seeing the deer first. If you have a lot of trees east of the Mississippi, it probably a good reason to use a stand.
However during gun season in cold weather, there is more visability, the leaves are off the trees and not having a tree stand enables you to move and change positions, more rapidly. If you have a good chance to see a deer before he scents you, I wouldn't opt for a tree stand. For this kind of hunting, my opinion, tree stands are over sold.
If you sit in one place, year in and year out, a tree stand might be the best solution to a hold fast hunter. But not all hunters hold to one exact place.
