Ballard has now had several opportunities to endorse JB as the starting QB for next week. He's shied away from doing so every time. His 'I thought Luck was going to be the starter, so I'm not sure' line is a cop out, it's his way of wriggling off the hook.
Also, the way Ballard, Reich and Sirianni all have talked about what they value in a QB is interesting. It reminds me of what Commodus said to his father in Gladiator: None of my virtues were on your list. It's like hearing your significant other describe what they find attractive and realizing that they're describing someone other than you.
