Ranking fantasy winners of Week 4

1. Josh Allen, QB, and Stefon Diggs, WR, Buffalo Bills

Allen is on some kind of run right now, delivering three straight 20-plus-point fantasy performances capped by this 36.5 point clobbering of the rival Miami Dolphins. This one required a mere 25 pass attempts, in large part because of the Dolphins' decision to have cornerback Kader Kohou cover Diggs; Diggs scored 34.2 of his 36.0 PPR fantasy points on his six targets (out of seven total) in which Kohou was the closest defender. This quarterback-receiver duo should only keep it up as near-the-top-of-their-position performers against the Jaguars and Giants the next two weeks. -- Cockcroft
