I really doubt there's any friction between taylor and mccullum.
You're right about Vettori coming back into the team though.
Ross delayed bring on the spinners as long as possible. I hope he doesn't feel like he has a duty to bowl Vettori any earlier than he bowled Jeets, and I hope he continues to turn to Southee as his strike bowler.
All that said, I think Jeets has earned his spot ahead of Vettori right now. Hopefully Bond, Taylor and co will advocate this.
