Its a balancing act isn't it - at the moment we all seem to feel that we are a bowler heavy - especially if they are going for an extra containing options, Dawson, instead of an attacking one such as Rashid, Crane, Plunkett or even Sam Curran for a change of angle.
If we drop Ballance (who, for the record, has not actually batted badly thus far - his dismissals have been balls that did a bit apart from that first one) and Jennings now, we just got he the start of the same long road without ever really coming to a point where we understand whether they are good enough or not. So, the ideal solution is an opener in, Jennings at 3, Ballance 5, Bairstow 6, Stokes 7.
