The Sam Bradford era in Arizona has come to an end.  He was benched last weekend for rookie Josh Rosen.  

According to reports he has dropped from starter to third string.  Every game he spends inactive saves the Cardinals over $300k.

The Cardinals will have Mike Glennon backing Rosen up for the foreseeable future.  The winless Cardinals had to make a change and moving Bradford to third string was part of that change.  

How has Bradford made so much money and done so little in the NFL?
