The contentious banning of the third man up in ruck contests has won praise from some of the game's big men.

The rule, swiftly introduced this season, allows only two opposing players to compete for the ball at stoppages.

Additional players who impact the contest are penalised.

The rule change has been questioned, with fear it may lead to the destruction of the traditional ruckman, given the unique tactics introduced by some clubs, like letting the rival tall attack the stoppage unopposed.

Speaking to ESPN, SUNS ruckman Jarrod Witts has hailed the controversial rule, saying it could see an influx of bigger bodied, traditional-sized rucks in years to come.

"I quite like the rule. I think there are a few clubs trying to exploit it at the moment. [But] I'm sure that will sort itself out in the coming weeks," Witts told ESPN.

"I really enjoy competing just one-on-one. I reckon it's great for the big guys. It's really important for us and gives us a better chance to show off our skills.

"I think it increases the importance on the bigger blokes."
