Week 2 of the Fantasy football season is in the books and it's time to decide who to start and who to sit in Week 3. 

But before you finalize your roster for Week 3, you'll want to see what SportsLine Fantasy analyst Brandon Marianne Lee has to say. Lee is a radio host on SiriusXM Fantasy Sports Radio, an on-camera analyst for Fantasy Alarm, and a Fantasy contributor to The Athletic.

Now, she's giving SportsLine members 12 players who should definitely be in lineups for Week 3 of the Fantasy season. One we'll give away: Jacksonville Jaguars quarterback Blake Bortles.

"The narrative is that Bortles doesn't play well against the Titans, a divisional opponent he faces twice a year," Lee said. "But if you saw the tape from last week, the 2018 Bortles is a confident one. And I'm willing to throw him back out there if the team can't just ground and pound with Fournette. Once they get their bruising runner back in full, I'll put Bortles on the bench."

Lee has also identified an undervalued tight end "we need to start taking seriously." This pick could be the difference between winning your Week 3 matchup or going home with a loss.

So which 12 players absolutely need to be in Fantasy lineups in Week 3? And which undervalued tight end needs to be lineups? ... Join SportsLine now to see the list of 12 players to start in Week 3, all from a proven Fantasy expert who can give you a huge edge in your league.
