Practices in the mid day Houston sun would harden the troops. There is no doubt that the 1st few years, the players sustained an inordinate number of muscle injuries during OTA’s, TC, preseason and regular season practices, with the heat factor (dehydration, improper pre-activity preparation, etc). This has improved in recent years, but is still suspect.
The heat factor would beat down the opponent. The sun would fry the opponent’s bench. We only have to ask ourselves, how often do we have the roof open in extremes of heat???? How often are the players exposed to extreme heat and humidity in away games???
I think the hardened pros from 2002-2004 were Sharper , Glenn , Dunta , AJ , and Walker . The rest were ... when the going gets tough ... hey we're an expansion team ... it showed in 2005 . This does'nt translate well if your going to try to out tough someone .
