Five observations about the Dolphins this training camp (look away if you want happy-go-lucky platitudes about guys working hard and striving to get better): The Dolphins drafted Dion Jordan in 2013 to be a dominant, dynamic starting defensive end to team with Cameron Wake for a frightening pass-rushing duo. That didn’t happen last season. It isn’t going to happen at the start of this season because Jordan is going to serve a four-game suspension for violating the NFL policy on performance-enhancing substances. But if Jordan continues playing as he has been lately, it might be a long time before we see what all the fuss was about. Jordan came into camp noticeably bigger, stronger and undoubtedly healthier than a year ago. And the first few days of camp he looked the part of a dominant player, collecting sacks, batting passes at the line, he even intercepted a pass at the line and returned it for a touchdown.
