I think everyone knows clubs put effort into stopping this guy, just look at the EF. But is that necessarily a good thing? Look at Ablett, Fyfe, Danger and probably some others. All they mostly get is head to head match ups because coaches know if you send a tagger to them they'll still rack up 20+ touches while you're tagger does diddly squat. Ellis though? He gets tagged and he goes into hiding, clubs know it and that's why they bother doing it.
Also, I don't expect every body to be as good as those players listed but it'd be nice if we had at least one who was "untagable"
