If you want to win your Fantasy football league, you need to hit it big in your draft. Finding an Alvin Kamara-type player late in the draft or on the waiver wire can change your entire team's outlook.

And before you search for those players in 2018, you'll want to see what SportsLine Fantasy analyst Pat Fitzmaurice has to say. 

A former Pro Football Weekly editor and writer for over a decade, Fitzmaurice has also written for SI.com, 4for4.com, and other publications. Fitzmaurice finished second in FantasyPros' 2017 rankings accuracy contest and received a 2017 Fantasy Sports Writers Association nomination for best football series. If anybody knows how to find a diamond in the rough, it's him. 

One high-ceiling player Fitzmaurice loves for 2018: Bengals receiver John Ross. 

"There's an opportunity cost in spending a late-round pick on him, but the Bengals have a vacancy for a quality No. 2 receiver, and Ross won't get much face time with any shutdown cornerbacks as long as A.J. Green is on the field," Fitzmaurice told SportsLine. "And it doesn't hurt that he's reportedly been the star of camp for the Bengals."

Fitzmaurice is also recommending a quarterback who could go undrafted that has monster upside, and a running back that could go off for huge numbers if healthy. Anyone who drafts these players could hit it BIG.

So which low-risk, high-return players should you target in your Fantasy football drafts?
