Finding the perfect addition to your Fantasy team via the waiver wire can be the difference between winning your league or going home with nothing. And before you determine which players you should target on the waiver wire this week, you absolutely need to see what SportsLine's Pat Fitzmaurice has to say.

Fitzmaurice finished second in FantasyPros' 2017 rankings accuracy contest and received a 2017 Fantasy Sports Writers Association nomination for best football series. He's crushed other experts when given the chance and knows what it takes to win a league.

Now, he's done an in-depth analysis of the best widely available free agents entering Week 10. One we'll give away: Chargers wide receiver Mike Williams.

"Williams has had just one catch in each of his past three games, but two of those catches have gone for touchdowns," Fitzmaurice said. "He's scored four times this season and is averaging 18.8 yards per catch. The seventh overall pick in the 2017 draft, Williams is the sort of talented young player who could catch fire quickly. He's a big (6-4, 220), strong boundary receiver who has a size advantage against pretty much everyone who tries to cover him. He gets a favorable draw this week against a broken Oakland defense that was completely embarrassed by QB Nick Mullens and the 49ers last Thursday."

Fitzmaurice is also all-in on a SHOCKING quarterback who gets a highly favorable matchup this week. This player has a suggested bid less than $5 and could be a huge boost to your roster for the stretch run before the Fantasy football playoffs.
