He'll return to type soon enough IMO. Never has been a Test class opener, never will be. He's had the benefit of being played into form by an absolutely appalling Australian side, and I'll admit he's capitalised on that well -- but I don't see him fighting when the bad times come, as they undoubtedly will (everybody loses form at some point).
That was (and still is) my biggest problem with the guy. I thought he was pretty decent early on (mostly because I was 14 and he'd made runs against Australia
) -- decent technique, good enough temperament; all the skills to be a Test-class, if not world class, opener -- but once it stopped being all too easy for him, he ****ed off to the IPL and spent years belting terri-bad Indian seamers and flash-in-the-pan Australian domestic blokes all over the place to make big bucks, while quite clearly not giving two ****s about his red ball game. He's the Indian Shaun Marsh.
Then, like Marsh, he got reselected because he looks pretty when in full flow during T20s and immediately cashed in. Marsh is even softer than Vijay, so it's no surprise that Vijay's kept it going for longer. Yeah, he's performed pretty well since his recall. I just don't think it's representative of much.
Don't get me wrong, he should be selected for home series against Australia until the end of time; a greying version of Murali Vijay would undoubtedly ton up against the Aussies while collecting his pension, but at the end of the day I don't see any fight in him when batting stops being so easy. He'll just piss off back to the IPL and collect a big paycheck for cricketing mediocrity. That's why I flat-out don't rate the guy, and why no amount of hundreds is enough to change my mind.
