Arizona picked up its first win of the preseason edging the Oakland Raiders 31-27. What did we learn about the Cardinals based on their effort? Here's 10 things we saw from Arizona in its home opener. 1. Ryan Williams looks good. The running back from Virginia Tech saw his first action of the year and made the most of it. He looked sharp on his cuts and had a nice burst of speed on his five carries for 25 yards and a touchdown.
