Less than 24 hours after their season opener, the Miami Dolphins waived fullback Boomer Grigsby and have signed Casey Cramer, who most recently played fullback and tight end for the Tennessee Titans.
"I'm out," Grigsby told ESPN.com. "They said they wanted to go in a different direction and make the position more tight end-ish."
Grigsby was among the new front office's first signings in March. He beat out incumbent Reagan Mauia, the only other FB in camp.
"It just goes to show how short-lived the NFL can be," Grigsby said. "You have to seize your opportunities. I know I seized those four preseason games, but I guess I didn't seize my one regular-season game."
Grigsby didn't make any glaring mistakes in Sunday's 20-14 loss to the New York Jets. He wasn't called upon for much. The Dolphins handed off to running backs Ricky Williams and Ronnie Brown 16 times all game and only four times in the second half.
Part of the reason Grigsby won the job was because he was a better receiver than Mauia. Grigsby caught four passes for 36 yards in the preseason.
Grigsby, converted from linebacker last season with the Kansas City Chiefs, is 5-foot-11 and 250 pounds. He apparently he couldn't handle this new role the Dolphins are envisioning.
Dolphins quarterback Chad Pennington completed 26 passes on Sunday, and 12 of them were to tight ends. Anthony Fasano had eight catches for 84 yards and a touchdown. David Martin had four receptions for 53 yards and a touchdown.
Cramer is a more "tight end-ish" 6-2 and 250 pounds. He has played 27 NFL games, mostly on special teams. He has two career catches. Last year for the Titans he played five games, including one of his two career starts.
