"It's always good to mix it up in the rucks.
"You know being a smaller loosie, I've got to try and do something and turnovers is something that I've sort of worked on and tried to make my own sort of thing."
Coleman's coach Maurice Stone senior is also quick to support the nuggety flanker.
"I think he has done that consistently throughout the season and he has been a real asset in terms of that, turning ball over for us."
Stealing ball and turning over possession was vital in a game where both teams had similar attacking abilities.
Especially on the counter attack with both sides able to turn half chances into points.
All of Opotiki's points came from talented fullback Te Amo Wilbore who scored two tries a penalty and a conversion.
Both tries came from turnover ball deep in their own territory.
He combined well with his twin Te Hata to give Whaka all sorts of grief.
Stone senior said he expected nothing less from his Opotiki counterparts.
"Opotiki, we expected them to be quite hard, especially after their loss to Tauranga Sports last week.
"I'm thinking they had a couple of players out last week and so they put all of their eggs in the basket this week."
Stone said his side turned over to much possession to keep Opotiki in the match, something he'd be working on this week.
