It seems to me that the advice to pre-tenure faculty to not let yourself be seen as riding the success train of more senior faculty is in direct opposition to current trends in NIH funding. Sure, we all want to show what good, independent, senior author scientists we all are, but it is extremely difficult to secure a  grant (R01 equivalent) without the support of a senior collaborator. It is very hard to get tenure without a grant.

Wash, Rinse, Repeat.
