Cleveland Browns: 15 greatest offensive linemen of all-time

Greatest offensive lineman in Cleveland Browns history: #12. Alex Mack

Already with Eric Steinbach and Joe Thomas on the roster, the Browns added another stud in 2009 when they used their first-round pick on Cal center Alex Mack. He came into the league expected to be a star, as his NFL.com scouting report highlighted his ability to win on multiple levels while playing with a high motor.

"” Tall, athletic center with large biceps and a solid lower body build. Puts in full effort on every play, often getting downfield for a second or third block. Nimble enough to get in front of screens, trap block inside and eliminate linebackers at the second level. Keeps his legs moving once making contact with his target, often putting his man on the ground in the process.” — NFL.com scouting report"

As a rookie, he started all 16 games at center for the Browns, a feat he accomplished the first five years of his career. He missed 11 games in 2014 with a broken leg, but returned in 2015 to start every game, and made his third Pro Bowl appearance that season.

Mack then hit free agency and Cleveland was unable to keep him in town. He headed south to join the Atlanta Falcons on a five-year, $45 million deal. So far, that’s looked like a good move for the Falcons, as he’s been in the Pro Bowl all three seasons with his new team.
