Here is a story about two coaches, in identical circumstances.
Coach A has gone 4-20 and his pathetic offense averaged 19 points per game.
Coach B, however, has had a lot more success. His team has gone 17-5 and his offense has averaged nearly 31 points per game.
Coach B is clearly better than Coach A. Or, at least, he would be, if they weren’t the same person.
That is the story of Kyle Shanahan’s career with the 49ers when he’s had Jimmy Garoppolo and when he has not. Nobody is going to argue that Jimmy G.
