At the moment I wouldn't change anything, except our luck if it were possible. Two games in is far too early to start making changes when there's no obvious candidates to come in, and I count Richardson in that category, yes he's a good cricketer and yes he's capable of scoring runs but not in the top 3 just yet.
The number 3 spot "broke" Muchall last season and now after only two games looks like "breaking" Smith already, the last thing the club needs right now is to knock the stuffing out of another young talented cricketer before he's got a chance to establish himself in the side. I've watched Richardson enough over the last couple of seasons to know he's a really good cricketer and don't deny he deserves a chance, but I've also seen enough of Muchall and Smith to know that they are also good cricketers but at the moment being given the No 3 berth is like the kiss of death, and it would be a shame to "break" another talented player so soon.
If and when the inevitable happens and one, or two of the top 3 gets dropped, they will find it harder to get back into the side baring any injuries. Richardson stands a far better chance of getting in and keeping his place once the wickets flatten out and batting becomes easier, a bit hard on the current top 3 buts that's cricket.
Personally I'm quite happy to wait till after the Notts game to see where we are and then make changes if nessacary, I honestly can't see how swapping things about this early would benefit the team as a whole, it would be different if we had a Rudolph carrying the drinks, but we haven't so we've just got accept what we've got for now.
