Lol, please. The last QBs Purdue has had that were drafted were Curtis Painter and Kyle Orton, and that was years ago. Love Orton because he was kinda a fat slob and seemed like a fun dude and he had a good career, but seriously? NU has had 2 QBs drafted in the last 6 years and Thorson is gonna be a high draft pick as well. That will be 3-3 their last 3 starting QBs, not including Colter who split time with Siemien.
I can play this game too:
Close your eyes and pretend you're one of the top QBs in the country and you're down to NU and Purdue, do you really want to play for a school that's won 16 games the last 5 years (about 3/year), has a coach that may or may not bounce on them for greener pastures, or go to a world class institution that offers one of the best communications degrees in the country (Johnson's major), play for a coach he's very familiar with (his brother attended NU), play for a team that's had three 10 win seasons the last 5 years, and literally be handed the keys to a starting gig for 3 straight years under the tutelage of a QB coach who has put 3 QBs in the NFL in the very recent past?
Both school's have advantages and disadvantages here.
