Jerraud Powers has been running as the No. 2 cornerback over Antoine Cason in Cardinals OTAs. Cason has been a starter each of the past three seasons, but it's not a surprise after Powers brought home a three-year, $10.5 million deal compared to Cason's one-year, $2 million pact. Cason could fall back to dime duties with Javier Arenas highly experienced in the slot. A rangy press corner, Cason is best suited to the outside. The Cardinals are deep at cornerback one year after being thin.
