Elite play at the tackle position is highly coveted in today's pass-happy NFL, and rightfully so. Weaknesses at either left or right tackle can keep capable starting quarterbacks from playing their best and limit offenses overall. Having one of the 10 guys listed below starting in the trenches puts the quarterback and his offense in a much better position to succeed.

Here's a list of PFF's top-10 offensive tackles entering the 2019 NFL season.

2018 OVERALL GRADE RANK: 6

Turning 35 years old in late August, Staley will retire as one of the best tackles to ever play in the NFL. He’s been the epitome of consistency for the offensive tackle position, earning 81.0-plus overall grades in each of the past seven seasons. He’s also avoided significant injury over the seven-year stretch, playing 840 or more offensive snaps in each season. All signs point to Staley and second-year offensive tackle Mike McGlinchey being one of the NFL’s top tackle duos for however many more years Staley takes the field.

2018 OVERALL GRADE RANK: 12

Though Johnson did earn a career-low run-blocking grade (74.4) a year ago, he's proven in years past that he's more than worthy of a spot on this list. His three-year run-blocking grade (84.7) ranks inside the top-five among qualifiers, and his 79.9 pass-blocking grade in the same three-year span (2016-18) ranks inside the top-20.

2018 OVERALL GRADE RANK: 5

The addition of Brown at left tackle made the world of difference for a Seattle offensive line that finished the 2018 season ranked 17th in pass-blocking efficiency after finishing 29th in 2017. Brown allowed just 21 quarterback pressures from his 501 pass-blocking snaps on the year and surrendered just six combined sacks and hits.

2018 OVERALL GRADE RANK: 36

Injuries have cost Peters late in his NFL career, but his play when healthy is still among the best in the league. He earned career-low marks in overall grade (69.5) and run-blocking grade (62.3) across 970 offensive snaps in 2018, but all signs point to him bouncing back this upcoming season. He earned 90.0-plus pass-blocking grades and 70.0-plus run-blocking grades in 2016 and 2017, and he earned 90.0-plus overall grades in three of the four seasons before that.

2018 OVERALL GRADE RANK: 2

Terron Armstead has been in the conversation as one of the NFL’s most balanced offensive lineman in the NFL ever since his breakout season in 2015 where he earned a 92.6 overall grade. In 2018, the seventh-year left tackle was one of only two offensive tackles to finish top 10 in both pass-blocking and run-blocking grades, resulting in an overall grade of 87.7. For his elite play, he earned the top spot on PFF’s top 25 offensive linemen of the 2018 NFL season.

Armstead finished the regular season with a pass-blocking grade of 89.3, the second-best mark among offensive tackles. With only 11 pressures (seven hurries, three hits, one sack) allowed on 329 pass-blocking snaps, Armstead tied for the fourth-best pass-blocking efficiency rating (98.2) at his position. From a run-blocking standpoint, 2018 was Armstead’s second-best career effort with a 78.0 run-blocking grade, third among offensive tackles.

2018 OVERALL GRADE RANK: 9

Smith didn’t post a banner year in 2018 compared to his previous career-highs, but his 80.1 overall grade and 86.6 pass-blocking grade were still among the best tackles in the NFL. He allowed just 18 total pressures across his 596 pass-blocking snaps on the year, which marked a career-low for the eight-year veteran.

2018 OVERALL GRADE RANK: 3

Whitworth’s best may be behind him as he enters the 2019 season at 37 years old, but the longtime stalwart – even in decline – is still one of the best offensive tackles in the game. He earned an impressive 86.1 overall grade while also logging 88.5 and 78.4 pass-blocking and run-blocking grades, respectively, with the Rams in 2018.

Among the 64 offensive tackles with 3,000-plus offensive snaps played in the last seven years, Whitworth ranks third in overall grade (92.9) behind Joe Thomas (94.4) and Joe Staley (94.2). Whitworth’s 93.6 pass-blocking grade ranks second on the list, as well.

2018 OVERALL GRADE RANK: 4

Schwartz turned in career-highs in overall grade (83.6) and pass-block grade (85.6) this past season. He also finished the year ranked tied for fifth in pass-blocking efficiency (97.9) and pressure percentage allowed (3.6%). The epitome of consistency, Schwartz has played 1,000 or more offensive snaps in every year of his seven-year NFL career and has yet to earn an overall grade below 72.6 or a pass-blocking grade below 73.8.

2018 OVERALL GRADE RANK: 8

New Orleans’ brass has seemingly hit a home run with 2017 first-round pick Ryan Ramczyk, as the former Wisconsin product has been nothing but outstanding in his two years in the NFL. Ramczyk has earned 81.0-plus overall grades in each of his first two seasons in the NFL, all while playing at least 1,000 offensive snaps each year. He’s also earned 76.0-plus pass-blocking grades and 77.0-plus run-blocking grades in each of the two seasons.

Also driving our confidence in Ramczyk being the 45th-best player in the NFL right now is just how successful he was at the collegiate level. Before earning high marks with the Saints, Ramczyk earned a 92.3 overall grade, an 84.7 pass-block grade and a 91.4 run-block grade.

2018 OVERALL GRADE RANK: 1

The highest-ranked offensive lineman on the 2019 PFF50 is none other than the league’s top pass protector, Green Bay Packers’ David Bakhtiari. Earning 93.0-plus pass-blocking grades in each of the past three seasons, Bakhtiari leads all offensive linemen with 1,200-plus pass-blocking snaps played since 2016 in pass-blocking grade (96.8). He also leads all offensive tackles on the list in pressure percentage allowed (3.4%) and pass-blocking efficiency (98.1).

Bakhtiari received PFF’s 2018 Pass Blocker of the Year Award for his efforts this past season. From PFF’s Mike Renner:

“Bakhtiari is currently the gold standard for pass protection in the NFL. There are better run blockers and more impressive athletes playing tackle today, but no one is stingier in pass protection than the Packers left tackle.”
