Aaron Shampklin

The Dolphins opted to sign Mike Boone and Aaron Shampklin on Monday upon the bad news for Alexander Mattison. Neither is the power runner Mattison is, but they were the choices over Jamaal Williams, who is known to bulldoze his way between the tackles.

“When we work out guys, we base it on the facts in front of us,” said McDaniel, indicating the roster spots were earned in the tryout.

Perhaps the most important thing to note is McDaniel also said the team selected capable short-yardage backs in the past two drafts in Wright and Gordon II, along with key run blockers. If the Dolphins do feel strongly about that, it's more likely one of those two backs takes over the role Mattison may have had. But then one has to wonder, why weren't they in that position before the team felt the need to sign Mattison. Outside of Achane, this will be a situation to monitor.
