To put Taumalolo's performances in perspective, then-Sydney Roosters fullback Roger Tuivasa-Sheck broke the NRL's record for most running metres in a season in 2015 with an average of 217m per match.
Taumalolo is already averaging 250m this season - and he's doing it without the added advantage of kick returns and 80-minute games.
"Jason is a strong ball-runner," Dragons coach Paul McGregor said.
But the answer to limiting Taumalolo, according to McGregor, is easy.
"Tackle him," he said.
McGregor though, is refusing to believe beating the Cowboys without Thurston will be that simple. The Cowboys are also without Kangaroos forward Matthew Scott for the rest of the season and hooker Jake Granville for at least the next month, with a broken leg.
Former Melbourne playmaker Ben Hampton shifts from No 9 to replace Thurston, while bench back-rower Blake Leary slots into dummy-half.
"Any team that is without star players, they lift," McGregor said. "It can't be one, it's got to be collectively.
"Their coach will expect a little bit more of everyone. Not just one or two.
"They've still got some quality players in their footy team."
