Sheerly by accident, I saw the last half of the England/France game here in the US. (We get one BBC channel, and that seemed to be what they were broadcasting.)
I began watching after all the scoring was done, and only saw the scoring in the after-game replays.
I'll confess that, not seeing Rugby regularly, I miss some of the finer points of the action. It's fairly obvious when one side is running and passing the ball backwards in certain patterns, but once a player is tackled and goes down with the ball in his arms, I'm lost as to exactly how the ball is put into play once more. There 'seems' to be some hidden, arcane way in which the ball suddenly appears at the back of the pile of players, and then a .... pause... until someone grabs it up and they're off again. It's almost as if the attacking team retains possession unless they miss a pass or kick it. Is this the case?
...and I seldom see exactly WHY someone suddenly chooses to kick when it is not really a scoring attempt.
I also wish they'd show a close-up, slow-motion replay of a 'scrum' a few times, as I NEVER can tell exactly what happens inside the circle to move the ball to one side or another. (At least on an out-of-bounds throw in, I can see the action, though the trick of two guys hoisting another high to grab the ball seems rather quaint...so far.)

   The only 'play' that I was able to appreciate was that leaping block of a pass near the end of the game when a score was almost certain...now THAT looked a bit like the American football I am familiar with.

   I suppose I shall never really gain an appreciation of Rugby just from those rare times it is shown here.
