Frank Gore was one of the few 49ers who played well in today’s loss to the Colts, running 11 times for 82 yards and catching two passes for 21 yards. Which leads to the question: Why did Gore only get 13 touches?
That may be the question Gore wanted answered when, according to Kevin Lynch of the San Francisco Chronicle, he was angry at coach Jim Harbaugh at the end of the game.
RB Frank Gore was angry at Jim Harbaugh at the end of the game. For good reason. He had only 4 touches in the second half.
