If you want to compare impact and statistics, Clarke was rucking againstr Trengrove, who normally plays as a defender but has been thrown into the ruck because port doesnt have anyone else. They split possessions around the ground, the only clear advantage was clarke won an extra 20 odd hit outs. It is what you would expect somewhat of any recognised ruckman against someone like trengrove. Next week though is a challenge with either of grundy witts or cox. I still thought there were a number of opportunities where Clarke could have made a lead on the wing and would have been the perfect link up player but he just jogged through the middle.
