Were live at levis stadium, a Beautiful Day in norttern california, two days and counting until super bowl 50. Im with two time super bowl champion Brandon Stokley. Ive said if the broncos make it to the super bowl, its because of their no. 1 defense and if they win the super bowl, its because of their defense. Im starting to change that a little bit. Im starting to feel like the panthers are going to score some points and peyton has to come out huge. Hes got to. They have to have explosive plays and big chunks of yardage. This offense isnt made for the 12, 13 they need some points. Reporter all weekend they have gotten points in practice. Peyton had another good day today, deep pass to demaryius thomas.
