My guess is that if Wiese has a good game for the Boks this weekend, that could be the difference between winning and losing for the Boks.
The Springbok back row was well beaten at the breakdown in the 2nd half. Their contribution in the air was also poor. The Lions pack established physical domination, winning more rucks and collisions.
Duane Vermeulen is the most influential player on the pitch in terms of the Bok game plan under Rassie/Nienaber.
He organises the defence, takes the high ball, in addition to all-around back row play like turnovers and carries.
He is like Matfield in the pitch - a semi coach.
If Jasper can play for the Boks like he does for Leister, he could be a new Springbok great in the making. He is strong, but will he be able to translate this into a test level performance
