Just under 6 million matches for main 2 word search term, so fairly competitive but not Britney Spears I grant you.
The real point being, the site that was sandboxed has sub 2 million matches.
I also had one site in the sandbox for a year and another for just 2 months, both same link structures etc. I am convinced that if, due to keywords or site theme/content, you trip the sandbox then it's unavoidable. Links etc (unless getting 100's a week) will have no affect either way
