Your quarterback goes down, and you need a new one. So, you look at the stats on the site to find a guy who had a good couple of weeks. Plus, you saw an interview with the guy, and he seems nice.

Picking a player while letting your emotions play a factor is not going to mean you failed completely. Plenty of people have had successful teams with this method.
