Starkel was clearly the better QB last year and has to have a leg up going into practice. There are two things about Mond however that suggests it's too early to declare a winner though:
1) the clutch gene that tatimobile alluded to &
2) though at the end of the season he still was not a good QB, at the beginning he was truly horrible. Whether it's a question of his comfort level in adjusting to a higher level game or he was simply learning though experience, Mond improved substantially as the season went on. He seems like the type of guy that could really improve coming out of his true fresh season.
Look at the habitual masturbator! See how thin, pale and haggard he appears; how his eyes are sunken; how long and cadaverous is his cast of countenance; how irritable he is and how sluggish, mentally and physically; how afraid he is to meet the eye of his fellow, feel his damp and chilling hand, so characteristic of great vital exhaustion.” Dr Henry Guernsey, Plain Talks on Avoided Subjects (1882)
