This is spot on and where Billy can distance himself from his last 3 predecessors, to not just save his job but also be successful here. The last 3 coaches had glaring issues that they refused to correct after the second year. All three of them had roster/recruiting mismanagement issues and poor assistant hires, but also there were embarrassing off the field issues, poor attitude, and other factors that were pulling down the program besides just wins and losses. Because they doubled-down on their mistakes and had too big of egos to recognize them, there were few short-term solutions to the problems they created.
Because Billy has done a good job January through mid-August, he has a better foundation to work with for a faster turnaround. Not all of this team's problems can be solved mid-season, but some can so they can at least get a winning season. Where Billy can make the biggest turnaround for the future is what he does between year 2 and 3. Will he double-down on his mistakes like the previous 3? Or will he make the structural changes needed (i.e., new OC, different playcaller, special teams coach, etc.)? If he makes those changes for next year, then he could have a long career here. If not, then we likely have a new coach in 2025.
I know people assume he will stubbornly double-down cause that's what the other 3 did, but Billy strikes me as a more humble person that isn't fueled by ego. I'm not predicting that he'll make those large changes, but I also think it's too soon to write him off right now.
