"Every year starts new," he said. "Every year starts new. I don't feel like I need to prove anything. The coaching staff signed me to come on here to play the tight end position. Whatever plays they call, I'll execute them to the best of my ability. If it's more passing plays than I've had in the past two years, I'll be happy about it."

At 29 years old and with seven years of NFL experience, Allen is the elder statesman among Dolphins tight ends, a group that also includes fellow newcomer Clive Walford, Nick O'Leary, second-year players Mike Gesicki and Durham Smythe, as well as rookie Chris Myarick.

"He brings leadership, he brings energy, he brings effort," said Head Coach Brian Flores. "When we get him out there, in the past, he's been a good blocker, but again, the past doesn't matter. He's going to have to go out there and block and be productive when he gets out there. I think he's a good receiving tight end. That's something that we'll try to take advantage of if we can, but that's up to Dwayne. It's no different than any other player. If he makes the most of his opportunities, then he'll see more opportunities."

There's been no indication as to when Allen will be able to be a full participant, though he said he was hopeful he'll be ready for the start of the regular season.
