IRVING (AP)  Rob Ryan expected to be an NFL head coach by now, just like his twin brother Rex and their father Buddy before them.

It didn’t work out that way, but Rob’s not complaining. He figures the teams that haven’t picked him have made a mistake, and that the Dallas Cowboys are lucky to have him as their defensive coordinator.

Of course he thinks that. He’s a Ryan.

Big, loud and proud like Buddy and Rex, Rob also keeps up the family tradition with a variety of innovative, attacking defenses. Another common trait is being his usual, boisterous self when talking to reporters – especially this week, with his first game in charge of the Cowboys’ defense coming against Rex and the Jets in prime time on Sunday night.
