We have years of struggling to find a decent batsman to go in at 3, now we finally find one and people want him to open? Crazy. Trott is brilliant, leave him where he is. Plus, he'll probably have some variation of Bairstow, Bopara, Bell and Taylor behind him, which could go down like a pack of cards.
Compton is naturally an opener, ask him, he says it himself. He should be picked (as long as he's fit obviously), because he showed at the start of this County season that he can survive and grind out scores.
The two closest guys to Compton in terms of Division One runs are Rogers, who has 50 more in 12 more innings and Prince, who has 20 odd less in 7 more innings. Tells it's own story, with two quality Overseas players.
He won't get picked though, because he doesn't play for the right County. I'd expect Root to get picked. Which I think is a shame, because a tour to India and two back to back Ashes could destroy his career before it even gets going.
