I think Froch is slightly jealous of AJ's profile, I agree though he seems the most negative about him. That's not necessarily a bad thing, diversity of opinion is needed within the discourse (you yourself are a good example of that on this forum!).
**** off, the whole SKY team have been selling Joshua as a "great" heavyweight for about 5 years. I saw Spencer Oliver call him "the greatest heavyweight of all time" on SKY, and no one even laughed in his face. I remember AJ-Martin being billed as "THE heavyweight championship of the world" (not an IBF paper title) with a montage of Ali knocking out Foreman in Zaire, etc. playing at the top of the programme. Adam Smith's been ejaculating in his pants to AJ at ringside for 5 years or more, comically excited about what AJ will deliver. Does AJ deserve a ton of credit ? YES, he does. Has he received a ton of credit ? YES, and the rest.
