There is a great article in the Miami Herald by Armando today in his Miami Dolphins In Depth Blog titled Report: Williams, Brown Not Very Elusive.
In the article Armando references a ProFootballFocus.com article titled Elusive Rating 2010. It is a long article that talks about how they come up with a rating for RB's that does not include the play of the other 10 men on the field. If you want to read the article, here is the link:
The Elusive Rating takes into account a RB's ability to break tackles and run away from defenders. From Armando's article:
So how did Ronnie Brown fair in the rankings? Not very good. Again from Armando's article.
ProFootballFocus refers to this as its elusive rating. It measures a back's ability and performance independent of the blocking in front of him. This rating is a great equalizer in that it removes the advantages running backs that play behind great offensive lines have over those who do not.
PFF further states their elusive rating filters out coaching and playcalling, as well as the other 10 guys on the offense.
How about Ricky Williams?
The good running games in the NFL have RB's with the ability to either gain yards after contact, can make defenders miss, or can out run defenders. What would you think of the Phins run game if the RB's would have gained an extra yard, like Darren McFadden did over Ronnie Brown, after contact? The Phins ranked 21st in the NFL in rushing last year. They averaged rushing 27.8 times for 102.7 yards per game. Imagine adding 27.8 yards per game by having a RB gain an extra 1 yard after contact. If that was the case the Phins would have rushed for 130.5 yards per game. At that mark, they would have ranked 7th in team rushing. If the Phins RB's average 0.5 yards more per carry more after contact, they would have ranked 13th. Maybe the RB's are more to blame than the OL for a lack of running game last year? I'm just saying. Armando sums all this up:
their numbers confirm what your eyes should have been telling you:
Neither Williams nor Brown were very good at gaining yardage on their own last season. Neither was good at breaking tackles or running away from tackles.
