I was watching the WC in 2017 and found that Bosch in the series was seriously disappointing at flyhalf. That was in respect of especially decision-making and all aspects of performance, The backline in that series only functioned when Willemse playing at 12 was first receiver cutting out the aimless play of Bosch.
Bosch came away from the WC with a much reduced reputation - Willensse with a much enhanced one,
I am not really impressed with Du Preez at flyhalf either and Bosch was no better than him when laying a few games at flyhalf. Maybe Bosch was hyped too much - he has defensive problems - but his decision-making is not that hot either, .
