The big difference between leaf and Luck is Leaf had all the physical skills but mashed potatoes between his ears Luck in many cases calls his own plays, I have seen reported Also, for those who remember, manning was supposed to have an average arm at best Luck supposedly is quite the cerebral player....... Great work ethic.......... Positive team leader........ Anything could happen, but Luck I think is the real deal So........ Its about the mashed potatoes......... Leaf had them for brains
