Which of the following QBs has the best chance of keeping his starting job for the entire upcoming season?

It would def. be Jake Delhomme. He just signed a big contract for like 5 years, so I don't see anyone taking his starting job away from him. Garrad also has just as good as a chance, because they don't really have anyone to good backing him up that would take over. Orton could easily hit a slump and be replaced
