Week 2 of the Fantasy football season brought a ton of new surprises, disappointments and questions that still need to be answered.

But before you try and separate fact from fiction after just the second week of the NFL season, you need to see what SportsLine Fantasy analyst Davis Mattek has to say.

Mattek has been working in the Fantasy industry since his college days and has contributed to virtually every meaningful publication and website in the industry. He's hosted podcasts with over two million listens and been nominated for several FSWA awards, including Football Writer and Best Podcast.

Now, he's breaking down the action from Week 2 to see what has changed in the Fantasy landscape.

One thing we learned: 49ers running back Matt Brieda is a startable RB2 every week.

"Alfred Morris is going to retain Fantasy value in the 49ers offense because he is still the more likely of the two running backs to get goal line work and actually finished with more carries than Brieda did," Mattek said. "However, Brieda is clearly the more explosive and valuable player in Fantasy. Brieda had a 66-yard touchdown run that showed off his patience as a runner and his elite athleticism. We can't count on long touchdowns every week, but knowing he has that in his locker makes him a better week to week play than any Colts running back, Marshawn Lynch, Jamaal Williams and other similar plodders."

Mattek has also identified a player you should trade for right away, and who it is may surprise you.
