I sort of agree, we've brought in (since time begun) some duds.
But, and it's a canny but, under this present regime I'd be interested to see where on Carr's list our actual in comings lie. If the two you mention were his no. 1 choices then I'd be more than a bit worried but if I had to guess I'd say that he brings his list of potential players into the club and they go for them more on price than suitability.
