In a game intended to showcase the all-stars of the NFL, nothing gets too serious at the Pro Bowl and things are laid-back. Playbooks are a lot thinner and players smile much more often than usual.

But for a pair of Japanese coaches, everything is an eye-opening experience and a chance for them to soak up every move the NFL's top players and their coaches make.

For the third straight year, two Japanese collegiate coaches have been invited to participate in the Pro Bowl week through a program of the Koshien Bowl (Japanese national collegiate championship) Project Team (KBPT) in conjunction with the Hawaiian Tourism Authority.
