Maybe. I'm not really fussed about Big Bash form or fielding off his own bowling tbh. I think they'll find things can get a lot worse than a mid 30's average.Remember Archer isn't English and has only been there a few years, he knows Australian conditions well and has played well here. I think he would be looking forward to a trip here and more bounce and pace.
I don't know what else they have coming though, but I don't think Archer will suffer here. he's proven he can bowl fast here and is a good fielder off his own bowling- His Cutting catch was great.
