RhodesRhodes and Rolle are the same age (27). Both have been very durable. Both have been productive.
Scouts Inc. offers this analysis on Rhodes: "Rhodes has size, athletic skills and functional play strength. He has deceptive speed and physical toughness. He shows good speed and quickness as a blitzer. He has been a very physical and productive player coming off the edge in zone dogs. He has good closing speed underneath. He takes good angles when supporting the run but can be inconsistent in this phase of the game."
The Cardinals already have a strong run-defending safety in Adrian Wilson. This looks like a good rebound move by Arizona.
