The Vontae Davis trade and release of Julius Pruitt altered the projected 53-man roster from Kevin Nogle at The Phinsider. But since he's the hard working blogger he is, there's an adjusted one right here.
In this projection, there are 27 total players on offense and 23 on defense. The noticeable change is obviously at the cornerback spot, since Davis is no longer on the team. Sean Smith, Richard Marshall and Nolan Carroll will see the most time at that position.
Here's a quick note on Davis' roster spot from Nogle:
Jamaal Westerman takes the roster spot of Vontae Davis, for now. I don't think the Dolphins go into the season with only four CBs, but, I don't think the fifth is on the roster right now.
