Bill Davis gives a great news conference. He's expansive and informative and never condescending to a questioner. He maintains excellent eye contact, moves his hands in gestures that are both welcoming and non-distracting, and often tells the truth. When he speaks about the Eagles' defense, even if the defense is not performing well, he is reassuring, because once Davis is finished speaking, one comes away from the conference thinking, Well, at least Bill knows what he's doing.
The trouble with Davis's news conferences - those he has given over his first two years as the Eagles' defensive coordinator, anyway - is that he's had to be reassuring too frequently.
