Goff and Stafford are mirrors of each other. Stafford peaked in year 3 at age 23 when he had that 5,000 yard and 41 TD season and the Lions won 10 games and made the playoffs. Goff was 23 at the start of the 2018 season and had 4,600 yards and 32 TDs and went to the Super Bowl.
From 2012 to 2014, age 24-26 seasons, Stafford regressed. He had only a 59% completion percentage, 83 QB rating, and 48 INTs. Stafford had talent around him. He had, at various times, during this stretch Calvin Johnson, Golden Tate, Pettigrew, Bush and Bell.
Goff from 19-21 regressed, age 24-26 seasons, and had a 65% completion percentage, 89 QB rating, and 37 INTs. Goff was better during this down stretch, however, a narrative was started because the offensive genius of our generation benched Goff for Wolford (LOL), and paid a 1st round pick to make him go away. Stafford stayed in Detroit and remained irrelevant.
In 2015 Stafford was paired with Jim Bob Cooter at age 27 and took off. Probably Stafford's best season as he set career highs in QB rating and soared to a 67% completion percentage and kept the turnovers down. Stafford would go on to play at this level for the rest of his career. Jim Bob Cooter is an afterthought. No one wanted to hire him as head coach. No one gave him credit for resurrecting Stafford.
In 2022 at age 27 Goff is paired with Ben Johnson. A TE coach who never called plays at the NFL level, and Goff had one of the better seasons of his career. He set a career low in INTs and his QB rating jumped to 99.3. Goff has continued to play at this high level ever since. Ben Johnson, who has never called a single offensive play without Goff as his QB, gets all the credit.
