How Solid was Arizona's Victory over Miami?


How solid is a victory when analyzed by the Football ERA algorithm when both teams score positive results, and there isnt a great difference in the spread between their results? In most cases, the team that comes out ahead has posted a good victory, but if their opponent gets a score that is a positive number, then they have earned their score by doing some good things on the field as well. This is because, normally, the algorithm scores both offense and defense, resulting in a negative score for the team that goes up against a dominant performance. In other words, a great performance pushes an opponent into the negative the higher a team earns positive points. As the formula calculates positive results on offensive gains, for example, the opposing team loses points on defensive calculations as well. Thus a dominant performance by one team over another ends up producing a result where the team that keeps accumalating more and more positive results pushes their opponent further and further into a negative result.
In the case of the Cardinal's victory over the Dolphins, Miami did a lot of good things to stay in the positive while ultimately losing out to a performance where Arizona did a lot right to earn a result that shows they had done more to control the line of scrimmage.







Arz … 743.16
Mia … 236.435










Miami was able to make some positive strides in the loss despite shuffling their lineup against a decent Arizona Cardinal team that returned all starters from Week 1 (see earlier post on Arizona's Week 1 win over the 49ers). The Dolphins, on the other hand, lost Rookie right guard Donald Thomas to an injury during their week 1 loss to the Jets and started Ikechuku Ndukwe in his place. On defense they rotated in more of their younger burgeoning players as reflected by the changes in their starting lineup from week one (highlighted in Bold).

Defensive Front:

Quentin Moses...Channing Crowder...Akin Ayodele...Joey Porter

Kendall Langford.....Phillip Merling(R).....Vonnie Holliday


Offensive Line:

Jake........................Sampson...............................Vernon
Long(R)..Justin Smiley..Satele...Ikechuku Ndukwe...Carey
