The winning streak happened, but it's so last year. Also, while the results are there in the record books, they mask that some of the performances were less than convincing.
In 2018:
Ford / Faz: Won - ITA, WAL. Lost - SCO, FRA, RSA x 2
Other Combos: Won - RSA x 2, JAP, AUS Lost -, IRE, NZ (just)
While there are a multitude of other factors at play, Ford / Faz isn't now clearly and obviously our best combo.
Maybe put it to the people - what question would we ask? Perhaps a televised debate?
