Come on mate, if Cook continues in his current form which is fairly likely given, that he is only 30 then he will end up with close to 12000 test runs with an average close or just over 50. These are phenomenal number for an opening batsmen rivalled by no-one from my generation post 1990. Hayden viru and smith come close but I find it even more impressive cook has done it consistently over such a long period of time.Only because he plays a ridiculous amount of tests and has been playing since he was 21.
Forget his stats he has also dominated and won man of series awards all over the world inc India aus and the UAE. Only South Africa eludes him and I wouldn't bet against him changing that in the next few weeks!
