Dolphins don't waste time getting better

There aren't many above-average defensive starters available in free agency that are still in their prime.  There are even fewer after the Dolphins signed two of them in the last 24 hours.

The Parcells/Sparano/Ireland triumvirate continued their aggressive overhaul of the Dolphins by re-signing inside linebacker Channing Crowder and signing Gibril Wilson, formerly of the Giants and Raiders. 

Crowder is 26 and was the best young inside linebacker available, along with Bart Scott.  Wilson is 28.  There are differing opinions about his skill level, but he's a thumper in the run game.  Miami's defense will be big and tough to push around. 

Wilson's signing makes it likely that Dolphins safety Yeremiah Bell will hit the open market as the best safety available.  But Bell is 31 and the Dolphins decided Wilson was a better value, which makes you wonder about Bell's skills. 

The Dolphins are smartly not resting on their 11-5 laurels, and they continue to get younger.  Bill Belichick is probably wishing his old boss had opted out of his Miami contract when he had the chance.

Update: I'm an idiot.  The Dolphins signed Bell later Thursday.  Wilson will move to free safety.
