Two things that you can definitely say about Manning are he is super competitive and has elite work ethic. I think the only way he would consider coaching seriously is after he retires he misses the competition of NCAA/NFL football. I don't see he him ever being more than a QB coach for UT. If he turned out to be a horrible OC/HC we would have to fire him. Imagine that ish, Manning fired from UT! And that would hurt his legacy here too. But with Manning being such a perfectionist, i don't think he could handle being a coach. He would drive himself nuts! Seriously he would never sleep! HAHA! He then would have to turn to crack/meth to keep his energy up! By the time he was fired he would have no teeth and weigh 110 lbs. HAHA! Alright I took that too far...my bad. I think T.V. would be more realistic and that would be a couple years after retiring.
