Last offseason, the Cardinals notoriously traded for Eagles QB Kevin Kolb.
Kolb was expected to thrive in an offense that featured Beanie Wells, Larry Fitzgerald, and Early Doucet. Kolb went 3-9 in his first season for the Cardinals. He was riddled with injuries, and was eventually outplayed by backup signal-caller John Skelton.
HC Ken Whisenhunt has established the fact that—even though the Cardinals sacrificed a lot of talent for Kolb—there is a competition at the quarterback position. If Skelton outplays Kolb again, the Cardinals may want to opt out of the Kolb deal or even attempt to acquire quarterback Peyton Manning.
Manning could be the team savior for Arizona. If the Cardinals ditch Kolb and convince Fitzgerald to stay in the desert, Manning would be in a perfect spot to revive not only his career, but the Cardinal team in general.
The Cardinals were 8-8 last season and narrowly missed the playoffs. Manning would immediately increase the level of play of the Cardinal team, and would bring their playoff chances back to life.
If I were Whisenhunt, I would be dialing up Jim Irsay right now. If the Cardinals could acquire Manning somehow, they would suddenly emerge as an explosive, scary team.
