Every Monday, we’ll bring you five key storylines borne out by PFF's grades and data. Here’s what stood out in Week 8.

QB Dak Prescott, Dallas Cowboys

PFF Grade: 92.0

Prescott set season highs in touchdown passes (four) and big-time throws (three) while not making any turnover-worthy plays. He went 25-of-31 for 304 yards, with his lone interception on the day coming on a tipped pass that was behind the receiver. The game marked his first time recording a big-time throw rate above 7.0% this season (9.4%).

WR CeeDee Lamb, Dallas Cowboys

PFF Grade: 91.1

It was only a couple of weeks ago that Lamb was calling for more involvement in the Cowboys' offense, and he followed up an impressive Week 6 showing with an even better outing against the Los Angeles Rams. From 35 receiving snaps, Lamb racked up 12 receptions for 158 yards and a pair of touchdowns. He also set a season high with a 4.51 yards per route run figure.

QB Will Levis, Tennessee Titans

PFF Grade: 77.9

Showing promise in his first career start, Levis put up some eye-popping numbers for the Titans in their win over the Atlanta Falcons. The rookie went 18-of-28 for 234 yards and four touchdowns. While Levis' stat line was boosted by a big showing from wide receiver DeAndre Hopkins, his 7.1% big-time throw rate in the game was the best by a rookie quarterback this week and tied for the fourth best this season.

DI Dexter Lawrence, New York Giants

PFF Grade: 95.0

Lawrence had his best game of the season in the Giants' loss to the New York Jets, earning a 94.7 PFF pass-rushing grade. He racked up 15 quarterback pressures, including a sack and three hits. He finished the game having registered pressure on 42.9% of his pass-rushing snaps. Lawrence also impressed against the run, with two tackles resulting in a defensive stop from 14 such snaps.

DB Mike Hilton, Cincinnati Bengals

PFF Grade: 91.7

All over the field for the Bengals in their win over the San Francisco 49ers, Hilton made an impact both in coverage and against the run. He registered a pair of tackles on 10 run-defense snaps, both of which resulted in a defensive stop and one of which was for a loss. Across 26 coverage snaps, he allowed just two receptions and made another tackle resulting in a defensive stop. Hilton also had an interception on a play nullified by a roughing the passer penalty.
