Will D.bucannon start this week?

Will D.bucannon start this week? AZ depth chart shows t.jefferson is the starter.
Is bucannon a better long term option than whitner Elam or either safety in BUF?

Bucannon is pretty unlikely to start Week 1. Although I expect him to become the starter sooner rather than later, it's likely going to take a couple of weeks at minimum. I think Whitner has top 15 potential. I'd go with him.
