I determined this last year. The universe has a property like dark matter called manning juice. Know one knows exactly what it is but it exists in limited quantities. Last year there was not enough manning juice near peyton. As a result the bones in his neck crumbled and he needed 8 surgeries. However most manning juice gravitate around Eli. This manning juice was so powerful it even caused balls to stick to Mario manninghams gloves.
This year the juice is flowing to peyton and eli's streak of 200 yard games is broken. Scientist are still trying to determine if there is enough manning juice in the universe to have a true manning bowl.
