Bit harsh calling him a 'journeyman at' 25-26. If he'd gotten his test debut at 30-31, fair enough. But 25-26, he is probably just about ready to come into his prime.
Someone like Graeme Swann didn't get his test debut until he was almost 29, and at 32, now already has 150+ test wickets, and almost 100 ODI wickets.
His age isn't an issue, if anything like a couple of others have said, it might be a positive. He'll be more mature as an individual, and hopefully that will also show itself in Sunny the cricketer.
Early doors of course...
