Every Monday, we’ll bring you five key storylines coming out of PFF grading from Sunday’s action. Here’s what stood out in Week 4.
PFF Grade: 91.0
McCaffrey had another standout performance for the 49ers, picking up 106 yards on 20 carries and finding the end zone three times. He forced six missed tackles and 54 of those rushing yards came after contact. He found the end zone as a receiver, too, and averaged 3.74 yards per route run. In all, he recorded 71 yards from 19 snaps as a receiver. Through four weeks, McCaffrey has racked up 600 yards of total offense.
PFF Grade: 93.3
Collins was on the field for only 24 snaps as a receiver against the Pittsburgh Steelers but still put up some monster numbers. He averaged 7.0 yards per route run, racking up 168 yards on those 24 snaps. He found the end zone twice and forced four missed tackles, including one on Steelers’ cornerback Patrick Peterson on his way to one touchdown. Collins is now quietly on pace for 1,800 receiving yards this year.
PFF Grade: 92.3
In a bounce-back game for a player who has been heavily criticized to start the season, Khalil Mack took Raiders quarterback Aidan O’Connell to the ground six times. Across 38 pass-rushing snaps, that meant that he recorded a sack around once every six pass-rushing opportunities. He added three hurries, too.
PFF Grade: 91.5
Bland faced eight targets from 29 coverage snaps and gave up four receptions for 69 yards, with three of those four receptions going for first downs. Turnovers were the story, though. He took advantage of an awful throw and decision from New England Patriots quarterback Mac Jones at the end of the first half and returned the pick for a touchdown. He didn’t score on his second interception, coming on fourth-and-2 with 11:49 left in the third quarter, but again got in front of a bad throw by Jones.
PFF Grade: 91.6
Winfield was solid enough in coverage this week, giving up three receptions for 12 yards from 42 snaps in coverage to go with one forced incompletion to his name. He dominated against the run, though, with three of his five tackles resulting in a defensive stop. Winfield also notched a sack as a pass-rusher. He had one of the most important plays of the game, too, forcing and recovering a fumble as the Saints tried to get some breathing room from their own end zone.
