the separation of test and limited overs sides is far from the positive move it's trying to be presented as.
it indicates firstly that the Strauss/Flower model of attritional test cricket, slow scoring rates and bowling dry is going to continue. the attacking, innovative play from T20 and ODI that others are bringing in to the test arena is not to be for us - we will be left behind. Alex Hales can forget a test future.
secondly, you've just seen a World Cup dominated by players that are generally stars in their country's Test side, and the Aussies won it with the majority of their test side. simply put - your best players are your best players, and can generally cross formats easily. the inference is that the ODI side will therefore be populated with the likes of Morgan, who could never cut it at Test level, and Hales, who England don't trust at Test Level.
it's a retrograde step showing that Strauss really doesn't have a clue. He's seen the power hitting in the World Cup, thinks he better push that way without realising the likes of Warner, Mccullum and De Villiers are proper players, not sloggers.
