The biggest issue on running attack for the Dolphins won't be related to any RB/HB, but the upgraded offensive line. There are significant signs that Sparano is pleased with his current starters and he trust on his roster members to backup them.
The most recent clue about it, is the fact that based on a close Parcells-Pioli relation, front office traded two o-linemen (Ikechuku Ndukwe and Andy Alleman) to the Kansas City Chiefs for an undisclosed 2010 draft choice.
That deal can result dangerous as Donald Thomas is returning after two injuries and Shawn Murphy needs more development to succeed.
Last season was marked with Donald Thomas first week injury and lose for the rest of the year, and former center Satele failing against mammoth NT, forcing to use a creative offense with the introduction of the now famous Wildcat package, a formation based on very old school offensive schemes.
Today with new center and the return of Donald Thomas, this offensive line looks upgraded to the point that creates such protection than anyone on the backfield can run effectively.
That includes one of the strengths of this team, a running unit that one time was considered a "two headed monster", now is a three or even four headed monster as with: a healthy Ronnie Brown (who also leaded the Wildcat)), a rediscovered Ricky Williams (who won't be as dominant as in 2003 but can share the load and still create big plays), the multifunctional Parick Cobbs (a favorite of Sparano) and even Lex Hilliard (now on his second season looks promising).
This way 2009 Dolphins looks like having the old school style of running unit of 70's Dolphins.
The Wildcat package, where a RB gets direct snap, serves to privilege a run and create options that sometimes transform in pass. But as Sparano and crew have expressed may be upgraded in order to stay as effective as last season.
I believe them, as this coaching staff have shown a respect for fundamentals and a creative way to use them. This is also confirmed with one piece of the draft: Pat White. He's a QB with the abilities of a RB, so under the Wildcat, he increases the possibilities for passing options.
These means it won't be the same Wildcat that Ronnie Brown leaded, but one that is being implemented as I write.
This new version of the Wildcat (Wildcat 2.0, WildPat or however you may name it) won't be exposed during preseason games, but for the next two games it's expected to see Pat White using the same Wildcat of last season as practice for the new one.
The big fact for next two games, is there's no position competition or a big number of doubts on O-line nor backfield, but to enjoy the running power of the team, and perhaps to watch some Wildcat moments.
