Any rule against you sliding in front of a player moving to the try line, so you effectively arrive parallel but in front of the line? Basically so you block the try being scored without tackling the player?
In what regard? Why would you not want to tackle the player, is it due to being in an offside position?
Tackling a player may not result in being able to stop him scoring, but blocking his path to the try line esp if he is also going low....
Just musing, not really too worried either way.
