Telling Cuthbert to go to the site and follow sources when there literally are no sources suggests to me you didn't even read through the site yourself before posting. If merely claiming "Sources - Press releases, news & articles, online encyclopedias & databases, industry experts & insiders. We find the information so you don't have to!" is enough to impress you then fair enough, but salarysport is complete and utter **** and them putting numbers next to names without any supporting info shouldn't be trusted.
