I'm thinking the only way England is going to make any progress is if they go with :
Strauss
Trott
Bell
Morgan
Bopara
Prior (wk)
Swann
Bresnan
Tredwell
Shahzad
Tremlett
Give Swann a bash at #7, the crux position that could restore some balance to the side instead of hoping Collingwood, Bopara and other part-timers will "do a job" when in fact all they do is concede a few runs with not a lot of threat and when we need the wickets that can be costly (missing a proper fifth bowler)
Swann
WC 2011 : 4 inns, 52 runs @ 26.00
15no off 9 balls vs IND
9no off 5 balls vs IRE
16 off 20 balls vs SAF
12 off 8 balls vs BAN
In terms of batting position over his career :
7 : 1 inns, 12 runs @ 12.00
8 : 10 inns, 159 runs @ 17.67
9 : 19 inns, 174 runs @ 11.60
10 : 2 inns, 6 runs @ 6.00
Worth a try, if he comes in late then it is no different to batting down the order at 8-10, if he comes in early (before the late slog) then it gives him a chance to play a more constructed innings.
He averages 24.70 in Tests with an SR of 82.42, not quite the same pressure to score runs quickly but he has done so regardless including 85 off 81 balls against South Africa, and 47no off 40 balls, 36no off 26 balls, and 63 off 55 balls against Australia. He's also scored a couple of other 50s, slightly slower, but shows he can play steadier/longer innings when needed.
WC 2011 : 9 wkts @ 23.56 (SR 32.67, ER 4.33)
2/35 vs HOL
1/59 vs IND
3/47 vs IRE
1/29 vs SAF
2/42 vs BAN
