Mike Duffy, of 49ers.com, reports San Francisco 49ers LS/TE Brian Jennings said his primary focus is on his health, so he can play as long as possible. "My goal isn't necessarily to snap the ball accurately," he said. "I don't spend my offseason just doing that. I spend my offseason trying to make myself a better person physically, spiritually, emotionally and mentally. The by-product of that goal is that I snap the ball accurately."
