... Dolphins special teams coordinator Darren Rizzi will not simply hand the job to Grant this year. In fact, it might be more of group effort than in years past.

Grant's biggest competition seems to be Danny Amendola, who was the Patriots' featured guy a year ago.

"We’re trying to really get more of a stable of returners and see who those are going to be," Rizzi said. "I think if you look back yesterday during our punt period, we had some guys back there. Obviously Amendola is back there, [Albert] Wilson is back there, Drew Morgan is back there. Those are guys that can really field punts. Kenyan Drake is a guy that can do it throughout his career."

Rizzi added: "I like to have as many options as possible. .... I think here would probably be a little bit more of a situational thing. I don’t think he’s going to be back there every time, for sure; but again, it’s great to have as many guys on the roster that can do it, the better we are."
