"I can certainly relate," Manning said ... "It's about being flexible, being adaptive."
"I couldn't throw the ball the same way after my injury, but you learn to use your experience and football intellect. That's what he's doing. He's adjusted his game and his swing and using his experience and using other parts of his body to get some strength and power."
"For a golf fan, it's great to see him back out here."
Manning was also REALLY impressed with some of Tiger's shots -- and judging from the video ... you can see why.
