Whatever. The 3rd tackler is always part of a wrestle and never, repeat never, needed.
I'm not actually against the idea. But it will dramatically change the type shape of players in FG. Less need to get across to make as many defensive efforts. More need to win the first collision rather than step it. More incentive to cash into the line than try to get through a gap.
It's quite a dramatic shift & as artificial as any other rule we've added lately- a flat our limit on who can tackle who & how. It will need fiddly buts around try scoring situations & areas- unless you want constant bereaver tries from 2m out...
I'm just not sure you've thought it through vs allowing a one the last meaningful contests in the game which may just "settle in" (given we've only just changed it.. again) & became a rule which is easy to grok & police & forces a ;ump to think before he smashes into a smart little man, and another avenue whereby an aware footballer can take advantage of a tired lump with a smart play.
Instead of banning it, existing calls like , "held", "release" could be called clearly to reduce other impacts of the strip or attempt & when it is allowed/speed up the play. Put onus on the stripper to get themselves the F out of dodge once the ref calls held/release.
Better ideas than completely changing who can tackle who.
