I have already conceded that Sutcliffe deserves to be in the top group, but the reality is that in direct comparison with Hobbs he always comes out second best. Hutton and Gavaskar pips him for me because they were the best openers for their teams and of their respective eras. No disrespect intended for Sutcliffe at all.
Hammond I compare to Weekes and Walcott. Exceptional records but holes in their records. A number three batsman should be capable of being defensive if required but also of being assertive and capable of destroying quality attacks. From what I have read and discerned Hammonds career strike rate was somewhere in Sutcliffe's neighborhood. Not good enough in my opinion for my first or second drop batsman.
Additionally you point out his record vs his strongest opponent, and while Australia had a strong attack, during his career it was primarily a spin attack and he was exception vs spin and medium pace. The only strong pace attack of his era was England and the West Indies. He couldn't face England, and he struggled badly vs the W. I. This is supported not only by his stats but by tour reports and anecdotal accounts. For me again that is not good enough for my first drop batsman for the ATG first XI.
This is not to say he wasn't an ATG, but like Weekes it keeps him from that very top elite tier.
Viv, Sachin, Lara, Chappell, Ponting all rate above him in this regard in my opinion. You don't have to agree.
You personally don't rate Lara or Viv, I don't question you as to why, despite the fact that both are seemingly rated above him by most historians, journalists and former players.
