You can also get stuff on the Saracens site http://www.saracens.com (where this is from) but the videos don;t work so well on my computer.

Iolo, I welcome the debate! I would say that Saracens don't seal on many, if any, of their tries or good attacks, they go beyond the ball. Whether they stay on their feet is a different matter.

"Research" is via Sportscoding of lots of games. The seal will stop the player at the ball. Top sides cannot afford to do that.

The discussion will continue! It might be a discussion of the exact nature of the seal though.
