What happened: The trade sending Marvin Harrison Jr. from the Cardinals to the Texans closed an underwhelming stint in Arizona where the wide receiver never reached his ceiling. Per ESPN's Josh Weinfuss, Harrison grew unhappy as frustration mounted over the direction of the offense.

Why it matters: For Houston, acquiring a premier perimeter target upgrades the passing attack immediately as the regular season progresses. Arizona clears the slate to reset its receiving corps rather than letting offensive discontent linger in the locker room.

What to watch: Harrison continues integrating into the Texans' offensive scheme as Houston pushes through its regular-season schedule.
