Because obviously they weren't prepared enough and shouldn't have been in those spots. If they were prepared they would have executed.
Great coaches (and leaders in general) take full responsibility for the failures around them. You're in charge for a reason.
That's before we even get into the fact Franklin wasn't putting people in situations to succeed. Schemes that didn't fit his players, awful play calling, horrible decisions on PT (Kaytron for example), bad strategic decisions (not going for 2 vs Oregon with an exhausted defense), etc
You allegedly "coached" for 25 years...hopefully you took more accountability for your team's failures than you claim.
