These are the stats for tackle efficiency last season, i have ranked them from most effective to least effective.
Tualau 94%
Woods 93.6%
Tolman 92.8%
Klemmer 92.2%
Fualalo 91%
Jackson 88.9%
Elliott 88%
RFM 87.8%
As we can see, Tolman sits 3rd on that list. Yes you also have to take into account minutes played per game, tackles made, etc. But the gap there isn't massive like some people are trying to make out.
Tackle efficiency isn't even an absolute true indicator when judging a players overall defensive ability, things like dominant tackles, slowing down the ruck, positioning, etc aren't even taken into calculations here. It's just does the player make the tackle or doe he not.
Does Tolman make his tackles? Yes. Does he cover extremely well in defence? Yes. No one is saying he doesn't do this stuff. But does he hurt in the tackles enough? No. Does he dominate the tackle enough? No. Does he slow the ruck enough? No. Things like these are equally as important as just being there and making a tackle. Like Mason said, Tolman is a spot player and teams RUN at him to setup the next play.
Some people need to stop making out that Tolman is some elite defender and that he justifies huge minutes because this, it simply isn't true. His teammates are just as capable at making NRL standard tackles while providing far more with the ball in hand. If Tolman is playing more minutes than Woods or Klemmer next season then that will be an absolute crime.
