The support comes just days after the Warriors fell to 14th on the NRL ladder following their lacklustre 30-14 loss at home to the Dragons on Friday.
Despite winning just four of their 11 games, Warriors' TV ratings are understood to be up around 40 per cent in New Zealand this season.
The Courier-Mail's Mike Coleman echoed Rothfield's stance, writing a column on Saturday calling for the NRL to axe the Warriors.
"Why are we bothering? Surely there are other clubs that actually want to play in the NRL?" he wrote on Saturday in a piece titled "Time to punt dud Warriors".
The Warriors will be out to prove a point as they take on a firing Broncos side at Mt Smart on Saturday night.
The Broncos currently sit second on the NRL ladder but will be without a number of key players away on State of Origin duty.
