False narrative. The QB is the most influential position on the field. The roster has been NFL average (at least for two years). The coaching I would argue has been NFL average. If Kyler needs a great HC and great GM to win a playoff game, don't pay him because he is not worth it and we don't have those yet and there is zero indication we will.
Kyler is entering year 4 without a meaningful win along with zero good performances in games to clinch a playoff spot or win a playoff game. The babying needs to stop.
