Are you trying to find support to back up the 20% number, or just the  
fact that traffic goes down? If the latter, there should be little  
controversy: Any redesign (assuming something more than cosmetic) is  
bound to result in URLs that don't work and search engine indexes  
that need to catch up with all the new links, often from scratch.  
Without an airtight server redirect strategy, this is almost  
unavoidable. Even without the confusion users might get when seeing a  
site's nav change, these factors alone can cause a huge dip.
