I'm in the minority here but I think Manning.
Tebow in the much bigger market but if the "Tebow" formations don't go well then it may be minimal playing time for him. When people don't play, their jerseys don't sell. I think I heard somewhere that his jerseys sold like mad after he got drafted....then hardly sold anything the year and a half he rode the bench....then went off the charts when he started games.
When you don't play, the jerseys don't sell. Peyton will play....until he is paralyzed in week 4
