What Selwood does and what Lynch did aren't really the same though. Lynch bent over and put his head down to truck through a tackler.
Selwood spots a tackler and makes minute changes to his body position - drops his shoulder, leans in, lowers his body - so a legal tackle ends up high. A lot harder for an ump on the field to adjudicate.
Opposition players simply have to avoid tackling him in the upper arm/chest area because he'll inevitably draw high contact, whether its the initial point of contact or if he shrugs the tackle higher. Go for the waist and if he gets the ball away, so be it.
tbh though I wonder sometimes if he does more harm than good for Geelong. Drawing a free kills their run and the opposition gets time to shift back.
If there's anything the umps can do, its a change of philosophy. Rather than punish high
contact, punish high
tackles. While the head is sacrosanct, any tackle that slips high isn't going to cause any harm, like a coathanger would. So any tackle that starts legal, should stay legal, even if it slips high. Similar Rugby League. You guys in League above the shoulders all the time, but its simply due to the nature of a physical game. They still punish high tackles and head slams though.
Only thing better than watching Geelong loose was watching Lindsay Thomas getting absolutely disrespected by the umpires. All that over acting had to catch up at some time. Great stuff.
Even watching the replay I thought Thomas dropped to his knees a little too easily. I was happy for the ump to let it go.
