It's Week 10 in the NFL, and that means that it's time for the contenders to really show their colors and separate from the pretenders.
It also means that your fantasy football league has clearly defined winners and losers as well. It's around this time of year that the legitimate contenders in leagues across the country start to pull away from the bottom feeders and prepare for the playoffs.
That doesn't mean the season is over, though. There are still important decisions to be made, especially with Aaron Rodgers and Robert Griffin III taking the week off along with many others.
Chances are, the schedule will throw a wrench in your plan this week. Very few of the matchups in Week 10 pit a great quarterback against a terrible defense, which means that underrated signal-callers could rise up and take control. There are still safe options, but it's very important to do the research and make the right decision.
With that in mind, these five quarterbacks are must-starts this week. Starting one or the other could be the decision that makes or breaks your chance for a fantasy football title.
