Cricket is a Wierd sport. Mainly for how it's played.
But in football, if you are having a lean spell, a bad run, you go on the bench, or don't get picked for the national squad. When the goals return. You are back in.
Cricket due to the national team playing all year(especially if you play all formats) when your out of form you have to knuckle down and get through it, if you don't and enough people call for your head, your out and out for a while even if the runs start flowing st county level.
Do I believe hales needs dropping? Nope, wasn't long ago him and Roy had a few hundreds between them.
If he get no runs at all this season, he will be watched in the next series closely, and if he's still struggling, he may be replaced. It's just a case off if there's someone out there to replace him?
