I watched the game for the 2nd time, and Leroux was even more of a disaster than I thought.
He was so bad that playing with 14 players may have been better.
He made more mistakes than the rest of the team put together in the 1st half.
His blunders led to two tries conceded against the run of play, and he made numerous other errors that allowed the All Blacks to get ascendency.
He certainly needs a rest, as with any players that play too many games without injury, eventually losing form.
Kolbe, Frans Steyn or Goosen could cover fullback in his absence- assuming he regains form.
At his best, he gets many backline attack movements going.
Goosen could be a solid bench player as he can cover flyhalf, fullback, outside center, and even wing. And he has a good boot to cover pole kicking- and provide another kicker on the field. He has a big boot, so he can play a similar territory game like France Sten.
