Sleepers and value picks make or break fantasy football seasons every year. Last year's biggest sleeper was arguably New Orleans Saints running back Alvin Kamara, who started as the team's third-string running back before taking the reins and amassing 1,554 yards from scrimmage and 13 touchdowns on just 212 touches.
Kamara was likely the NFL's best value pick as well, but sometimes there's value to be had even in the front end of drafts.
For example, Los Angeles Rams running back Todd Gurley's average draft position was No. 17 last year, per the Fantasy Football Calculator.
