The spotlight has been turned upon the Storm's so-called grubby wrestling tactics in the past week, but statistics show Melbourne aren't even close to having the best defensive ruck speed in the NRL.

The Storm have been the centre of attention since Souths general manager Shane Richardson took aim at the club in an extraordinary attack last week.

Storm CEO Dave Donaghy returned serve, describing Richardson's comments as "stupid" prior to Melbourne's 22-18 loss to the Raiders last weekend.

The issue then went into overdrive on Monday when Cameron Smith was handed a concerning act notice for squeezing the head of Canberra's Bailey Simonsson while using his knuckles.
