Katich should've been captain years ago, in fact if they should even hand the reigns over to him now. However, as a replacement for Clarke as 'future-captain' - his age rules him out maybe, although i wouldn't mind it for a few years. I'm not completely against Clarke atm either, and i would give it to North ahead of White (even though White is the better captain, i still rate North higher when it comes to quality of test player.)
