LAST EDITED ON Jun-24-12 AT 03:31PM (MST)[p]Some of the difference I have noticed between CO and UT.
In my opinion, tag numbers are the answer. In 1999 CO cut deer tags IN HALF. In the early and mid 2000's they enjoyed some of the best overall quality mule deer hunting seen in any western state in decades. Since 2007 they have also suffered through some rough winters and have lost lots of deer. But, because they still have proportionally much less pressure on their bucks than states like UT and ID, they consistently have higher buck to doe ratios and higher trophy quality. In my opinion, UT could have buck quality equal to or greater than CO. However, it would probably mean about 40,000 more deer hunters sitting out each year in addition to those that already can't get a tag.
There is a big difference between growing more deer and increasing buck quality. Population trends and overall deer number in CO don't look that much different than they do in UT over the last few years. Both states have had some bad winter losses recently. However, CO did make major cuts to buck tags on the units with the biggest losses, UT did not. Quality has bounced back relatively quickly in CO.
CO isn't some magical Mule Deer Shangri-la, they just have decided to give up opportunity for higher quality. UT has done the same thing for elk, while CO manages elk for opportunity. NV manages for buck to doe ratios similar to those of CO, but NV has much fewer deer and less deer habitat.
There are other factors too.
CO does have a lot of really good deer habitat, more than UT.
There is more private land and fewer large contiguous chunks of public. Often management on private parcels is beneficial to public land hunters.
Interestingly, CDOW doesn't do any coyote control, and doesn't allow hound hunting for bears. They are really conservative on bears and lions.
They also don't do anywhere near the habitat improvement work that is done in UT.
Either all the predator control and habitat work in UT haven't been effective at growing deer numbers, or if they are working deer numbers would be REALLY low if we hadn't done anything. Something to think about...
Just some of my observations.

There is no such thing as a sure thing in trophy mule deer hunting.
