SEATTLE -- During his first training camp as Seattle Seahawks head coach, Mike Macdonald kept his players on their toes with what he called mystery situations. For one period in every practice, he'd pit the No. 1 offense vs. the No. 1 defense in a specific scenario that would be unknown to both sides -- even offensive coordinator Ryan Grubb -- ahead of time.
A two-minute drill one day, a four-minute drill another day, the offense backed up on its own goal line, a sudden change in which the defense has to defend a short field after a turnover.
