About midway through Tuesday's practice in one-on-one drills Dolphins rookie wide receiver Chad Bumphis put a double move on cornerback Brent Grimes turning him around and then caught what would have been a 50-yard touchdown pass. Bumphis the undrafted free agent from Mississippi State is gaining attention in training camp by making plays something few other Dolphins receivers have done recently. He's not big (5-10 202) or especially fast. His strength is crisp routes and a knack for getting in and out of his breaks which is how he gets open. "He understands how to play that slot receiver which is not an easy position" offensive coordinator Mike Sherman said. "You have to be nifty and crafty and he appears to be that." Bumphis had a game-best five receptions for 85 yards in Sunday's 24-20 loss to Dallas highlighted by a 45-yard reception. On a team searching for a fourth receiver that's a good thing. And with receivers Rishard Matthews (leg) and Julius Pruitt (leg) slowed the door is open a bit wider for Bumphis. Of course nothing is secure. In the Dallas game Bumphis "floated" into a route according to Sherman and had a Ryan Tannehill pass glance off his hands and into the hands of linebacker Devonte Holloman who returned it 75 yards for a touchdown. It was a memorable but not defining play. "He's definitely got a ways to go" Sherman said "but he's a great guy to work with." Observations --With quarterback Pat Devlin (hand) not practicing the Dolphins altered their routine so the healthy quarterbacks – Tannehill and Matt Moore – wouldn't throw an inordinate amount of passes. The same might happen Wednesday. --The defense returned to its bullying ways shoving around the offense. Now they have to do it against an opposing offense. --Kicker Dan Carpenter was 3-for-3 on field goals hitting from 52 51 and 47 yards. They were all strong kicks right down the middle. --Defensive end Dion Jordan had his quietest practice in a week. No sacks few pressures. But he still seemed to play fast.
