When the Detroit Lions have all five of their offensive line starters together, the impact on the offense is undeniable. The run game is better, quarterback Jared Goff is markedly better when he faces less pressure, etc.
For Week 16, after facing a blitz-heavy Vikings' defense, Pro Football Focus named the Lions' offensive line their offensive line of the week. On the PFF Team of the Week, center Frank Ragnow got the nod at his position, as did right guard Graham Glasgow. Defensive backs Ifeatu Melifonwu and Brian Branch got nods on the defensive side.
"The Lions’ starting offensive line allowed only five pressures, with all five starters earning PFF pass-blocking grades of 69.0 or better."
Detroit Lions have the top two offensive lineman by PFF grade through Week 16
It seemingly has been adjusted a bit, to 92.5, but Lions' right tackle Penei Sewell has the top overall grade for an offensive lineman from Pro Football Focus through Week 16 (93.8 run blocking grade, also the highest in the league). Not just offensive tackles, all offensive lineman in the league this season so far. If he didn't have the number of penalties he does, six or seven depending on the source, that grade would be even higher.
Ragnow is No. 2 among all offensive lineman with an overall PFF grade of 88.1. He has not allowed a sack in 863 total snaps through Week 16. What he's doing is even more impressive when you consider he's battling an ongoing toe injury, a back issue has been something he's dealing with and he had meniscus surgery on the knee he injured in Week 13. He's better in a compromised physical state than most centers are fully healthy, and based on current PFF grade no center has been better this season.
Elsewhere on the Lions' offensive line, among all offensive lineman in the league, Glasgow is tied for 13th in overall PFF grade (80.1) and left tackle Taylor Decker is 32nd (74.3).
