Saints Rush Hour: Success & Winning in the Rushing Attack

Sooo... what are the numbers in parenthesis after those other players listed?
Lol, if I had to guess, those are the number of multi-TD games for those players. I’m not sure bc it doesn’t make any sense the way it’s written. It would be impossible to surpass players at 16 games (which would give AK 17 games of multi-TDs), but not surpass a player that has 18 in that one game. It’s just a turrable piece of writing.
