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 9. One quarterback he says you should consider: Dak Prescott, who should see his value get at least a modest boost from the acquisition of Amari Cooper. 

"When we last saw him before the Cowboys' Week 8 bye, Prescott was throwing for a season-high 273 yards against a pretty good Washington defense," Fitzmaurice said. "He's also run for 149 yards over his past three games, with a TD run in each of the past two."

Fitzmaurice has also identified a player who has seen his value explode following the trade deadline. This player has a suggested bid of almost $30 and could be a huge boost to your roster for the stretch run before the Fantasy football playoffs.
