I could spend, and at Big Blue View probably have spent, thousands of words detailing the answer to that question. Let me try to boil it down.
After that 2022 season, mistakes were made. The Giants overachieved and still had a lot of rebuilding to do, but they acted like they were already built and made some short-term, short-sighted, moves.
Fast forward to 2023 and, after paying Daniel Jones, they completely abandoned the play style that made him successful in 2022 — and this year in Indianapolis. Instead of a play-action passer and distributor, they tried to make him a drop back passer and focal point of the offense. Daboll tried to make him Josh Allen. Which he’s not.
There have been too many draft picks who underachieved. The big debate is whether that was on Daboll and his coaching staff, or if players were improperly evaluated.
Daboll also allowed the Giants to lapse into a stage where players weren’t held accountable, and there weren’t any standards.
Finally, the hiring of Shane Bowen as defensive coordinator and Daboll’s insistence on sticking with him when it was long ago obvious it wasn’t going to work, was a disaster. The defense is terrible, despite the fact that it has enough talent to be much better than it is.
