Don't really agree with this at all. The reason we have picked a five man attack is two fold.Bell, Cook, Collingwood, KP, Tresco, Strauss have only 3 wickets between them in a combined 155 Tests. The only recent England batsman to make any contribution with the ball was Vaughan (6 wkts in 64 tests) and given his knee he is not likely to ever bowl again.
Every other country has a specialist batsman that can help with the bowling. England doen't, therefore we are forced to pick 5 bowlers and have a long tail.
Its time the batsmen stood up and allowed a team with better balance to be picked.
a) on a positive note: Flintoff
b) on the negative: the lack of a serious spinning option meaning we haven't been able to put out a balanced four man attack.
Nothing to do with the batters being able to bowl a few overs or not.
