The site is simply a tool provided for you to make informed decisions. You can go to multiple sites and get multiple opinions. As on this forum, folks give advice based on their opinions. No one is an expert in FF because no one is a fortune teller. You look at the matchups, how the players is playing, streaks, etc. and then make a decision based on your information.
As for Bruce, he's been nothing more than a 3rd WR and sometimes a 2nd this whole year. He's averaging 7.62 points per game in FF based on a 1/10, 6 for TD scoring model. Stats like that aren't going to carry your team so you really shouldn't be placing your playoff hopes on a player like that, if that's indeed what happened.
