The Indianapolis Colts are entering the 2025 season with a revamped offensive line, featuring two new starters, yet they still maintain their reputation as one of the top units in the NFL, ranked fifth by Pro Football Focus. Quenton Nelson and Bernhard Raimann form a formidable left-side duo, both earning impressive PFF grades last season, ranking fourth and eighth among their peers respectively. The Colts are relying on Tanor Bortolini and Matt Goncalves, who are stepping into key roles at center and right guard. Bortolini showed promise last year, but his inexperience at center may pose challenges, especially with the complexities of Shane Steichen's system.
