Like everyone else, I can't pick just one. Probably the entire ND and OSU games from last year. The OSU game is probably one of the greatest experiences of my life with my dad and brother in the student section with me.
On the flip side, though, for some reason the pick against Iowa that essentially killed any chances we had stands out to me just as it did the author of the article linked in the OP. As soon as I saw him collapse into Molk's arms something changed for me and how I watch college football. Denard wasn't great because of his athletic ability, he was great because he gave every single ounce he had on every play. These are kids. When they make mistakes, they're absolutely crushed, to a degree that I can't imagine watching from the stands or my couch at home. Who the hell am I to criticize.
Love that kid.
