| This page in a nutshell: A source's reliability doesn't immediately make it a good source. It's the content of the source that matters. |

Sources having significant coverage are not the same as sources being reliable. It's always important to check the content of the source(s), because if we as editors based notability on reliability, and did not read the source itself, then it would make the SIGCOV section of theGeneral Notability Guideline useless.
Of course, reliability is important. After all, it's probably the most important part of sources, but the content of the sources is arguably just as important. Take a well-known spokesperson as an example. If all of the sources were added because of reliability, you would not only run the risk of almost all of the sources being passing mentions, but also the risk of there being a lot of unproven information on said article.
All of the above examples can be written off due to sources being reliable without taking a source's content into consideration. Either they base it on how popular the source is without checking the source's credibility, or they base it on awards, such as theEuropean Newspaper Award. Either way, the result is an article with a lot of sources with any/all of the examples shown above that were added solely for the sake of reliability, which is something Wikipedia generally wants to avoid.
