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 16. One we'll give away: Packers running back Jamaal Williams.

"If you need to find yourself a running back for championship week, here's your man," Fitzmaurice said. "A knee injury to Aaron Jones leaves Williams as the Packers' main running back for Week 16, and he's likely to play more than 90 percent of Green Bay's offensive snaps. Competent if unspectacular, Williams offers run-catch versatility but not a great deal of big-play ability due to ordinary speed. He had 12 carries for 55 yards and a touchdown Sunday against a tough Chicago defense, and he added four receptions for 42 yards. Williams gets a decent Week 16 road draw against the Jets, and the potential for heavy usage makes him an attractive option for RB-needy Fantasy owners."

Fitzmaurice is also all-in on a SHOCKING wide receiver who has an extremely favorable matchup this week. This player has a suggested bid of $10 and could be a huge boost to your roster for the Fantasy football playoffs.
