No wonder the Cowboys held their camp in different spots besides Dallas for as long as anyone can remember. The heat index for Wednesday morning’s practice was in the triple digits and not much better for the afternoon session. Mercifully for the players, the Broncos and Cowboys decided to cut their joint morning work about 30 minutes short.

The Cowboys returned to their Valley Ranch headquarters after opening camp in San Antonio at the air-conditioned Alamodome.

One benefit of being back in Dallas is that it gives legendary NFL figures who live in the area the chance to attend. Roger Staubach, Lee Roy Jordan and Pat Summerall were among those who passed by Valley Ranch during Wednesday’s sessions.
