Yes of course.
A site-wide link to a page which is ranked very low (contact page) might effect the overall ranking.
I think that you mean over optimization, but I just wanted to ask: When you say ranked very low, do you mean that the page is over optimized and not looked upon too favorably by the search engines, or the page is not receiving a lot of traffic?
If you meant something else, I would appreciate if you could tell me.
