The package where Ronnie Brown lines up in the shotgun is called "Wildcat," inspired by quarterbacks' Coach David Lee's time last year as offensive coordinator for the University of Arkansas. The Dolphins utilized Brown on Sunday the same way Lee utilized former Razorbacks' running back Darren McFadden in 2007. Miami coaches installed the plays Wednesday during a practice that Williams called one of the most intense of his NFL career. ''I don't usually get tired at practice, but I almost had to tap out on Wednesday,'' Williams said.
