I think the only time I've ever heard about the T-Nation writers putting more of an emphasis on upper body than lower body was during the "20 lbs of hollywood muscle" article being that it would suit their needs better.
Other than that, most of the articles have alot of emphasis on leg stuff. Squats and dealifts are the two best exercises for your overall body, being that they pretty much work everything, and the GH release from all the major muscle groups firing.
I forget who gave this tip, but it was on a daily tip saying that you should begin every workout with a leg movement. Supposedly it makes your workouts more effecient. I've been following this for about 6 weeks, and I feel that its been helping.
I know you said "emphasis on upper body" and didnt say "only train the upper body" but for the majority of all activities, the legs are involved much more than the upper body, therefore IMO more important.
