Now I know I'll probably cop a bit of flak for this, but I've been thinking it for a while and I have to say it really.
Dalrymple is better than Strauss. Seriously. Strauss's record may look fairly decent - but he only averages 28.7 against ODI standard sides. Further still, if you take out a couple of series against a clearly substand West Indies bowling attack, he averages 25.4. Given he bats in the top order, it's quite clearly unacceptable - and I think everyone realises that. But what many don't realise, is that in the times Dalrymple has been given a chance to bat decent time, he's done well.
In 11 innings batting at #6, Dalrymple averages 33.4 - and that being in matches against Sri Lanka, Pakistan and Australia - quite respectable bowling attacks. He quite clearly is not at all good at "going the tonk" at the end of the innings and as a result failed when he was batted lower behind Flintoff and sometimes Nixon. This point was further illustrated in the fact that, even when he batted at #6, he was getting really good starts and then having to throw his wicket away at the end - he only failed to get past 20 twice from 11 starts.
Now, he could well fail up the order, making him a fairly useless player that can only play a half-measured Collingwood role before throwing it away when the time to really accelerate came, in which case he should be promptly dropped from the squad after the WC. But the signs are there IMO to suggest it is worth a go, considering the fact that Strauss is not only a poor player but is in poor form to go along with it. The worst thing England could do though, is replace Strauss with Dalrymple and then bat him at 7 or 8 or something ridiculous - he has to be at 5 or even higher as far as I'm concerned. Collingwood's effectiveness seems minimal when he comes in later than the 25th over really so he could well benefit from batting #4 (and if not, Dalrymple could bat 4 himself..), and on the wickets in this World Cup, Pietersen at #3 really makes perfect sense.
Now, if everyone in England was available, Dalrymple wouldn't be my first choice to bat in the top 5 by any means, but given the players in the squad, I think it's really worth a go. It'd leave a side looking something like this:
1. Ian Bell
2. Michael Vaughan
3. Kevin Pietersen
4. Paul Collingwood
5. Jamie Dalrymple
6. Ravi Bopara
7. Andrew Flintoff
8. Paul Nixon
9. Saj Mahmood (we all know it's going to happen..)
10. Monty Panesar
11. James Anderson
Now, I know that looks pretty strange on paper, and a side that an over-reacting imbecile who wanted to change things for the sake of it would post - but I think it's worth a go really for the reasons I've outlined above.
