I voted for Jake. He didn't have a perfect season by any means and made some really bad decisions in both EWU games, but he's still the best gunslinger we've had in a long long time and without a strong QB our offensive system just wouldn't work.
I can't bring myself to pick one over the other. Each player brought so much to the team. The faith and loyalty Doss had towards the Aggies to come back for his senior year is huge and, couple that with his immense talent, he could be my choice but Moe and Jake were leaders as well.
