2. There is more comfort in taking away from the offense than the defense right now
The big four on the chopping block this offseason were Keenan Allen, Mike Williams, Khalil Mack, and Joey Bosa.
Money inevitably had to be freed up, and those four had some of the bigger contracts in the building. Keenan, although expensive, appeared to be the one of the foursome who would survive the cut because of his connection to Justin Herbert and because he was coming off a major statistical season.
But when it came down to it, Khalil Mack and Joey Bosa got restructured deals and the foursome of Keenan, Mike Williams, Austin Ekeler, and Gerald Everett got the boot.
We can logically conclude from these major cuts on offense, and the simultaneous retention of marquee defensive players that Harbaugh and company want to focus on remaking the offensive personnel around Justin this offseason.
They are more comfortable keeping this pass rush together and getting it playing at its optimal level than moving forward with the aging and injury-prone offensive weapons for another season.
