Cub, I'm a five-day purist. Always have and always will be.
As I, and others, have mentioned already, T20 is at base level a cash grab which engineers a game in favour of the batsman. The BBL gave glimpses of hope in terms of changing the mindset of the format with some sturdy performances from the likes of Hogg, Warne, Lee, MacGill, Nannes et al, but the game has a long way to go. I found the BBL largely enjoyable because of the likes of the old heads squaring up against the up-and-comers. Was a crying shame to see Warner only play one game.
The basis of my argument is that I don't favour any format of the game that places one discipline above that of the rest. Test cricket is the ultimate arena for a cricketer to prove his worth.
