Anytime I audition for something, it's always a question of whether or not the people I'm auditioning for understand I'm an improviser and I like to do that, and if they like that or if they just want someone who's going to do what's written.
If you want to get a deal, negotiate with the teams yourself. Say, "I want this much, and no less, but I'll show up to camp on time." It doesn't seem that hard to me.
You don't want modesty, you want humility. Humility comes from inside out. It says someone was here before me and I'm here because I've been paid for. I have something to do and I will do that because I'm paying for someone else who has yet to come.
