If we take Ballard at his word, BPA is his style. I feel that is backed up by the Hooker and Quincy picks. I preferred Rivers over Basham, and of course the Pats took Rivers right after we took Basham, but he got hurt so we don't know if he's any better yet. I believe Ballard has also said BPA with the caveat that with similar ranked players, need would factor in, though he also stressed he wouldn't pass up a great talent for need. He's also stressed that trenches are THE place to build a team.
All of this is from memory, so it may be flawed. But I'm sure this can be verified via Google searches.
