Always found Mike Hussey's away/home differential a weird thing. At 'home' for WA, averages 41 (same as his away Test average) but 'away' for Northants/Durham/cbf, averages 71 (3 unbeaten triples help that a lot but take them away and his average is still a sky-high 61, the same as his home Test average). Compare that to a very average record in England for the Test side but scored a couple of great tons against stiff oppo in Perth for Australia. Dunno if the away/home thing is as big a factor as being made out. Have heard one theory that, having smashed CC bowlers to all parts, that he choked under the pressure of repeating the dose against the same bowlers in Tests. Certainly, heaps of his dismissals in England for Australia looked like faulty decision-making.
Also never really did well opening for WA but managed big runs in the off-season which goes part of the way to explaining why he didn't get a look-in for Tests until he was around 30. Was only when he started batting further down in OD games for WA that he started to build some momentum and nabbed a Test spot. Was rated highly by Marsh when at the academy so his name always came up when Taylor/Slater/Hayden/etc. were having a lean trot but don't think he was ever that competitive with them, mainly because he middled for WA.
Weird career in some ways. Personally, think he suffered by being asked to be the straight man in the opening partnership for WA for so many years. The blokes at the other end tended to be dashers who were a bit hit-and-miss (Campbell/Lavender/etc.) so he had to reign it in and I don't think that was ever really his game. Contrary to his rep, don't think he was ever a 'gritty' player, only when he was finally asked to be that 'busy' player for WA did he really take off.
