Cardinals' unrestricted free agents: John Abraham

My look at the Arizona Cardinals' list of unrestricted free agents continues with a player who was among the best edge rushers in the league but played just one game last season.

Next up: John Abraham, LB

Reason to re-sign: There's really only one reason why the Cardinals would want to bring Abraham back in 2015 and that's if he can regain his 2013 form, when he had 11.5 sacks and made the Pro Bowl. One of Arizona's liabilities last season was edge pass rushing, a position where Abraham has flourished throughout his career. Even if Abraham can prove to be productive as a third-down rusher, he may be worth bringing back.

Reason not to re-sign: On May 6, Abraham will turn 37 years old -- old by any standard in the NFL. He played just one game last season after suffering a concussion in Week 1 on "Monday Night Football" after missing all of organized team activities and minicamp, and most of training camp last season. A return in 2015 means Abraham would have played less than four weeks of football in a year. And another reason to not re-sign Abraham is that he likely will be facing a suspension by the NFL for his arrest on charges of DUI last summer.

Prediction: Abraham's road back will take too long and, at 37, he likely won't be the same impactful rusher he was in 2013, especially with so much time away from football. The Cardinals won't bring Abraham back.
