At the risk of dramatically oversimplifying things, this game will come down to which QB can make some plays and eliminate mistakes. The teams are likely fairly evenly matched. Wiscy has an inordinate number of 5th year guys but IMO that is not as meaningful as it once was. True freshmen and second year guys are no longer just role players in CFB, they are elite players. PSU also has a Iot of 4th and 5th year guys - Walker, Miranda, Holmes, Scruggs, the transfer from Harvard, Dotson, CSB, George, Clifford, Ekibite, Tangelo, Mustipher, Brooks, Luketa, Katshir, Brisker, Sutherland, TCF, Stoudt, Pinegar.... that's 20 by my count. If we lose this game it will not be due to a lack of experience.
PSU has the kind of team that should do well on the road in a big game - veteran experienced OL, deep talented RB corps, veteran QB, veteran K and P, veteran DL. No excuses this year.
