Where is Rocky Marciano in ATG and best HW lists?

[ICB]

I'm watching a documentary and although he was certainly a devestating fighter,I seem to think and the presenter certainly seems to insinuate that Marciano hand picked alot of his opponents.With this isn mind,does this tarnish his record and where is he in ATG and HW lists?
