Before the 2011 season even begins, the 49ers have vastly improved their coaching situation with Jim Harbaugh replacing Mike Singletary. "I have talked to two different players that each independently told me Singletary was a complete joke as coach, with no attention to detail or any concept of player development," writes Jeff Risdon in his season preview of the 49ers for RealGM. "He often overrode his assistants when they tried to implement wrinkles or use failures as teaching moments, and his insistence on forcing the clearly overmatched Taylor Mays and Chilo Rachal into the lineup damaged the spirit to win." Harbaugh is receiving good marks already "Harbaugh has already earned the respect and trust of the players, particularly the offense."
