[Editor's Note by Matty I] This is a very surprising move simply because, like you guys have pointed out, Davis was thought to be a "Parcells guy."  But I guess those bonds aren't as strong as we might think.  And with Renaldo Hill looking healthy, Davis became expendable.  I just wonder who would step in if, for some reason, Yeremiah Bell had to miss any time.  Who replaces him at strong safety? [end note]

Per Sun-Sentinel:

The Dolphins surprisingly released safety Keith Davis on Wednesday, clearing way for the team to fit four safeties on the 53-man roster.

Davis, who spent his first five years in the NFL playing for the Cowboys, signed to a two-year deal in the offseason. He was expected to compete with Yeremiah Bell for the starting strong safety spot, and contribute primarily on special teams.

But the emergence of Chris Crocker, who is presently starting over Jason Allen at free safety, and last year's starter, Renaldo Hill, who is recovering from an ACL injury he suffered last October, made Davis expendable.

[UPDATE]

From the Miami Herald:

This is a curious move for several reasons.

First: Davis has been starting on practically every special team the Dolphins play. He has, by all accounts, acquitted himself well on those special teams. So that causes questions.

Secondly: The team is under the 75-man roster limit. It didn't need to release anyone. So it raises eyebrows that Davis would get released when there was no roster mechanism that required the move.

I am not suggesting the move is caused by outside circumstances but it is curious.

I can share with you that Davis was listed on the team's flight manifest for Wednesday's trip to New Orleans. He was even given a room number. So this is obviously a last second move. The team offered no comment as to why Davis was cut.
