At center, that player was Tanor Bortolini.
In his second NFL season, Bortolini took over as the Colts‘ starting center. Over 566 pass-blocking snaps, he did not allow a single sack.
Among all centers, he ranked 16th in pass-blocking efficiency and third in PFF’s run-blocking grade.
“Bortolini had a breakout season and anchored one of the best offensive lines in football in 2025,” wrote Valentine. “The Colts finished the year with the second-best PFF pass-blocking grade and fourth-best PFF run-blocking grade in football.”
Bortolini’s overall grade from PFF was the third-highest at his position group.
