The game comes down to a matter of mistakes."Still, when he addre sed his team at the end of practice to Nathan Walker Jersey provide his a se sment of the work, Rivera said, "I told them that I thought it was exactly want we needed to do to go out and win a football game. I thought the tempo was what we needed." owner Jerry Richardson attended his first practice of week, having arrived in California on Wednesday night.
