I think you could argue in good faith that if we still had Wink we would have at minimum 2 more wins. Imagine the difference in narrative on Lamar if the team was 9-2 or 10-1 right now.
McDonald's been pretty good since the Miami game, IMO. Many people were raving about him after the past few games.
The Miami game seemed like a complete failure of scheme. The other blown leads, while certainly some blame must go to coaching, I put it equally on the players not executing.
