As a somewhat impartial observer I will have to disagree with you. I can only speak to Highlands because I haven't seen T & X practice but HHS puts in alot more time than we ever did as players, and when I played I didn't think you could be worked any harder. Sure it doesn't hurt that they get a fair amount of transfers to come in but they put their work in about 48 weeks a year. Also when they are done with thier organized activities alot of thier guys will go back and lift more. Culture is a big part of it but so is hard work.
