1. The Ravens have learned their lesson from 2001, when they entered training camp with no depth at running back and then found themselves crippled after Jamal Lewis went down with a season-ending knee injury.

Now, the Ravens have one of the deepest backfields in the league. Willis McGahee is a legitimate featured back. Mike Anderson is a dependable backup who could find his niche in the Ravens' one-back formations. Musa Smith is an above-average third-down back when he's healthy. And P.J. Daniels, a fourth-round pick in 2006, has become a favorite of the coaching and personnel staff.

2. While the Ravens had special teams practice in the McDaniel College gym, offensive coordinator Rick Neuheisel was working with Drew Olson and Troy Smith on the field. They were going over how to attack different coverages. This will be an interesting battle for the No. 3 quarterback spot, and both quarterbacks are working hard to win it.

3. By moving a couple of training camp practices indoors and canceling an afternoon one, coach Brian Billick has left himself open for criticism by adjusting his schedule to avoid the excessive heat. Some think Billick is too soft on his players. Billick thinks he is being smart by not exposing them to potentially dangerous situations.
