It didn't take Mychal Kendricks long into his first practice to figure out exactly what his new coaches were trying to do.
''I think the whole thing here is to make us feel uncomfortable,'' the new Eagles linebacker said, ''to see how much we can handle in a short amount of time.''
Welcome to the NFL, rookie.
Kendricks and 33 other rookies are among 44 players participating in the Eagles' three-day camp, which opened Saturday at the NovaCare Complex.
Although most of the players in camp will never play in an NFL game - in fact, 13 of them are unsigned rookies who are here on a tryout basis and not even under contract - the coaches will throw a lot at everybody in a short time.
Yes, they want to see who can handle it physically. But more importantly, they want to see who can handle it mentally.
''What can you do in a pressure situation?'' said Kendricks, a second-round pick from California. ''If you can handle it, you can pretty much handle everything.''
