MIAMI GARDENS — One week of training camp down for the Miami Dolphins, and a few more weeks of camp to go, although hopefully none is as dramatic as this past week. Cornerback Jalen Ramsey’s left knee injury dealt a crippling blow to the team and the defense. Ramsey, according to reports, could be out until December. But, as we learned from last season’s rash of injuries, the Dolphins have good depth and a good mentality.
