GREENWOOD VILLAGE — Within the first 12 minutes of the season, two of Cherry Creek’s best players were standing in slings on the sideline, and the Bruins already faced their first deficit. No sweat for a team looking to capitalize the D in dynasty, though. The Bruins did as they usually do — wear down their opponent with superior size, depth and skill — to roll Ralston Valley, 35-9, in the four-time defending Class 5A champions’ season-opener at the Stutler Bowl. “We had a lot of new guys coming in, a lot of guys who played before but haven’t started, and we had some first-game jitters,” Cherry Creek senior right guard Hayden Treter said.
