FB and G roster moves made

After just one game, the Dolphins have decided that Boomer Grigsby is not cut out for the role of fullback on this team.

Grigsby was cut, and the team has signed FB Casey Cramer.

Cramer (6'2", 240 lbs.) was a seventh-round draft choice of the Buccaneers in 2004. He has spent time with Tampa Bay, the New York Jets, the Tennessee Titans, and the Carolina Panthers. In Carolina, he worked with current Dolphins' Offensive Coordinator Dan Henning and offensive line coach Mike Maser.

Cramer can play fullback, tight end, and special teams. He is 26 years old.

If this move was made as a result of Grigsby's inability to serve as a lead blocker on run plays, you have to think that Parcells and Ireland may have made a wrong decision in choosing Grigsby over Reagan Mauia. Mauia obviously lacked the ball skills of Grigsby, but he was undoubtedly a better lead blocker. I really don't think the coaching staff should have prioritized the fullback's pass-catching abilities over his primary duty of opening up holes in the running game. Mauia has since been picked up by the Bengals, so you have to wonder if the team would have liked a re-do when choosing who to take into the season opener as their fullback.

The team also added G Evan Mathis. This move is possibly a reaction to the sprained left ankle that RG Donald Thomas suffered in Sunday's game. Even though Thomas played through the pain during the game, he was seen on Monday walking on crutches with his foot in a protective boot. There have been some whispers that Thomas' injury could sideline him for the rest of the season. Thomas, however, refutes those claims, calling them "definitely an exagerration." He says he hopes to be able to practice on Wednesday and play on Sunday.

I don't think this injury will be season-ending, but don't be surprised to see him sit out the next week or two, after which the team has a bye week. That'd give him three full weeks of recovery. Shawn Murphy or Andy Alleman could probably step in for the time being.

Mathis (6'5", 305 lbs.) was a third-round draft pick of the Panthers in 2005. He is 26 years old. He has played in 25 games in his career, starting 15. His most extensive action came in 2006, working under Dan Henning in Carolina, where he started 15 games at right guard for the Panthers. In those 15 games, he was only flagged for three penalties and gave up 3 sacks. According to FootballOutsiders, the Panthers were ranked 22nd in the league in 2006 when running up the middle, with an Adjusted Line Yard of 4.12.
