What happened: Hard Knocks Episode 2 showed GM John Schneider discussing bringing Arnold in before Seattle put him through a workout. Seattle was still evaluating Arnold after the tryout three days before the move.

Why it matters: Arnold's first-round pedigree gives Seattle another cornerback option during final roster evaluations. His arrival puts immediate focus on how quickly he enters the preseason rotation.

What to watch: Seattle's Saturday preseason game could clarify Arnold's initial role.
