that's an upgrade too obvious to ignore.
In 2022, 6 of his 12 Ints came in 2 back to back games (don't know what deal was in those 2 games, injury, supporting cast, etc) which means in his other 10 games he threw only 6 ints...hardly an int machine (which if you are worried about, Buchner should be a much greater concern in this department).
When you factor in the much less talented supporting cast he played with at Wake, if you use the same effort level you are in projecting Buchner as being special, it's VERY easy to project Hartman as being more successful with our supporting cast.
