I can't remember much about Brock's final season, but surely Bairstow is gaining more recognition and awards?
Also, people have seen Bairstow more, not just featuring but performing very well in international series against NZ...
To be able to choose between the two of them would be a great problem to have, Motum probably has more range, being able to hit the outside shot, but there's no questioning the hustle and inside play of Bairstow... It would come down to who surrounds them as to who would prefer better in different circumstances...
