Just so I have this straight: we lose to a bad Commanders team and their 3rd string QB. They then turn around and lose to a pathetic Vikings team, with RGIII back.
Meanwhile, the Cards only loss is to Denver, who by the way, is pretty good. but we are better than them.
Gotcha.
Your logic is unassailable
First of all you should know that you cannot do NFL math from team to team, week to week. You should know this as a fan of the game. Every team is week in week out very different based on a plethora of variables. The Jets took it to the Broncos and lost, and probably should of beaten New England 2 weeks back. Does this make the Jets a GOOD NFL team? No, but in your logic yes.
If Denver goes into New England with Osweiler at the helm and loses, does it mean that New England is better than a Manning led Broncos team? Not in any sense of reality does that mean a yes.
....and this is why you cannot make these assumptions.
It simply means that NE is better than an Osweiler led team.
Is Arizona better than a Weeden led Cowboys team? Certainly.
Is Arizona better than a Romo led Cowboys team? You cannot answer that with concrete evidence.
I do believe that Romo is able to hit his wide open targets and is able to throw to a receiver before the 4th quarter though.
