The ball is put in the scum in the loose head prop side in both codes (number 8 in league and 1 in union)
they are there to provide the push in the scrum and the heavy powerful ball carrying attack in the open play
nothing, there are hookers in the scrum who should hook the ball. The chances of the scrum being perfectly still is highly unlikely anyway.
Whilst the term "spots the ball" does not appear in the phraseology of rugby I'm assuming that you mean a Scrumhalf
In rugby union, a kick-off directly into touch on the full usually results in a scrum for the receiving team on the centre of the halfway line, but the receiving team has three options: the scrum, a line-out on halfway, or they can even choose to have the opposition kick-off again. In rugby league, a kick-off into touch on the full results in a penalty.
safety because the team collapsing the scrum has lost the ball
In rugby, a loose scrum formed around the ball when it is on the ground .
There are no records of scrum duration. In the 70's 80' and 90s scrums would last some 30 seconds from ball in. Now its about the same.
Scrum is a way of restarting the game, either after an accidental infringement or (in rugby league only) when the ball has gone out of play. Scrums occur more often, and are of greater importance, in union than in league. In both sports, a scrum is formed by the players who are designated forwards binding together in three rows. The scrum then 'engages' with the opposition team so that the player's heads are interlocked with those of the other side's front row. The scrum-half from the team that did not infringe then throws the ball into the tunnel created in the space between the two sets of front rowers' legs. Both teams may then try to compete for the ball by trying to hook the ball backwards with their feet.
At the back of the scrum and roams around the field during general play. Sometimes positioned in the middle of the field
This is a Scrum or Scrummage. The scrum half (number nine in Union) throws the ball in to the tunnel formed by the two front rows. To do this the Scrum Half stands adjacent to their open side prop forward. This is the one who has one side of his head (the left side) not in contact with the opposing prop forward. The ball must pass the feet of the open side prop before the ball can be hooked back by a front row player. No hand may touch the ball . The 2 sides endeavour to push the other off the ball so that they can win possession To learn more about rugby rules look on the IRB website - it has a wealth of information.
The number 8's task in Rugby Union is; In the scrum - bind on the 2 second rows and push them to support the drive forward, to take channel one ball from the hooker and hold or release to the scum half On breaking from the scum carry the ball and if in a push over try situation actually ground the ball once its at their feet. To attack the opposing flyhalf as a ball carrier (this is usually the weak point). To protect their own scrum half when they collect the ball at the base of the scrum. To retain the ball when a scrum is successfully pushed forward therefore gaining ground. To act as a ball carrier in all phases - tackle in defense Normally a line out jumper and used to "clean up" loose ball at the back of the lineout. Is one of the potential target receivers from kick off Is one of main receivers from opposing teams kick off In Rugby League the number 8 is the equivalent of a prop (RU No 1)
no its classed as a "knock on" and a scrum to the opposing team is given If the ball is deliberately knocked forward then a referee can issue a penalty
