San Francisco 49ers QB Jimmy Garoppolo has been more decisive in training camp this summer and shown a quickness mentally and physically that wasn’t always there previously, according to Jennifer Lee Chan of NBC Sports Bay Area.’When I say decisive, I mean just decisive when that ball is in his hands and out on his back foot. When he hits his back foot in his drop it’s a thing of beauty and you’re seeing more and more of it throughout camp,’ 49ers defensive coordinator Robert Saleh said.
