i am sick of seeing and hearing about the team tackle being classed as 'dominant' obviously when there is 4 or 5 defenders against 1 attacker we know who wins.
a dominant tackle should be classed as a 1 on 1 tackle that stops the attacker at the point of contact.
you should be rewarded for that whereas currently you are punished.
as for the 3 or 4 player team tackle - grab him and dance until the ref calls held, then drop him onto his back, then slowly peel off 1 by 1, it should be discouraged. maybe having the ref call held, followed by an agreed amount of time i.e. 3 or 4 or 5 seconds followed by a penalty if they aren't all clear. do it until they learn
