Time and a place for accelerating, you need runs on the board not batsmen back in the pavillion. Leave Trott alone, he puts on 60-70 or better and he'll have done more than a lot of the passengers in the side. You need a balance of batting, 300 may require a run a ball rate overall, but you don't need to score at that rate throughout. The general rule of thumb is double the score after 30 overs, if that is so then 150 runs should come off the first 30 and 150 off the last 20 which is respective rates of 5.00 and 7.50. You need to see off the new ball, preserve wickets and then take on the second string bowlers. Everyone walks out all guns blazing and we end up neck deep in doo-doo like in the 2nd ODI - 4-5 wickets down in no time at all.
And just when I thought England had taken a step forward they take one back by bringing back double O zero - the Bresnan
Shazhad showed why we need wicket taking bowlers, he was about the only one and we lost the 2nd ODI, so we bring back another so who is going to take the wickets? No good batting down to 11 (in theory), we need to be able to defend the totals and most of the batting should be done by #10
Shame I did my analysis of Yardy, Bresnan and Wright on BBC 606 not here. But I know Yardy took 3 wickets in his 1st and 7th ODIs and has taken just FOUR in the other 12 ODIs. Wright and Bresnan have batting SRs in the 90s, but that's no good if you're scoring like 10-20 when you go to the crease - Bresnan's batting average is in the 30s, but due to a lot of not outs. So besides Broad and Shazhad we have the promise/expectation of maybe a wicket or two. As spinners go, Yardy is economic but not a wicket taker.
Broad - takes wickets, can be expensive
Shazhad - so far has taken wickets albeit against Bangladesh
Bresnan - doesn't take nearly enough wickets, can be expensive
Yardy - economic but doesn't take enough wickets (10 in 14 ODIs - 6 in 2 ODIs, 4 in the other 10)
Wright - too expensive, not threatening wickets enough
Bopara - Ravi Bit-parta when it comes to bowling, six wickets @ 48.83 in 46 ODIs
Collingwood - useful, but how often does he not bowl his allocation?
