Interesting. So riddle me this:
1. tackle assist has released ball carrier, is over the ball and facing his own goal line.
2. ball carrier attempts to pop pass to team mate
3. tackle assist sticks hand out and knocks ball backwards.
Play on?
Does the tackled player let go of the pass? If so, play on (the tackle gate ended when the tackled player let go of the pass)
Does the tackled player attempt to pass but before he can do so, the TA knocks the ball out of his hands? If so, PK against TA for playing the ball from the wrong side (tackle gate still exists because tackled player still has possession of the ball).
Of course, you could always pre-empt the whole thing by trigger-fingering the TA for taking up the space! :biggrin:
IMO. YMMV
The thing is, I see where you are coming from, but both your view and my view are equally valid because there is no actual Law that covers this situation. And there wont be until the Lawmakers have the good sense to ...
1. Recognize in Law that the tackle is a phase of play and define when it ends (we already know when it starts)
2. Define the gate and who it applies to (and I mean use the term "tackle gate", complete with a diagram, in the LotG)
3. Define a Tackle Assist, and specify what he can and cannot do.
4. Include "taking the space" as a Law and specify a sanction
