"Ernie Sims is experiencing quite the culture shock coming from Detroit.Instead of hotels, he's staying in tiny college dorm rooms.Instead of training camp at the team facility, he's "in the middle of nowhere," surrounded by mountains.Instead of no fans being able to attend Lions camp during his early years in Detroit, there figures to be quite a few milling around today when the full pads are on for the first time this camp and more is known about what the Eagles have at a number of positions, including Sims' linebacking corps.Then there's the new playbook. It's not more difficult, he said, just different terminology than the one he mastered with the Lions."I don't read it as much as I read my Bible, but I read it enough that where I get sick of reading it," said Sims, acquired by the Eagles in a three-team trade in April.Sims stayed on the practice field for a few minutes after yesterday's practice ended, getting extra feedback and questions into the coaches and making sure anything he hasn't grasped gets ironed out before the first preseason game Aug. 13 against the Jacksonville Jaguars."
