Kevin Kolb--Cardinals New quarterback
The Cardinals traded cornerback Dominique Rodgers-Cromartie and a second-round draft choice in 2012 for Kolb, who has started seven games in four NFL seasons.
And the run that season and made the Pro Bowl the following year.
He didn't play as well in 2010, however, and coaches have consistently stressed to him the need to study and concentrate at all times. Rodgers-Cromartie has admitted he tends to lose focus.
The Cardinals drafted cornerback Patrick Peterson with the fifth overall pick this year, and Whisenhunt said he thinks the team has other young players ready to step in.
"Ultimately, Kevin was the guy we had the highest grade on," Whisenhunt said.
"There are no guarantees in this business, no matter who you are looking at. It's a very tough position to evaluate. It's going to come down to how we play and how Kevin plays."
