RIVER FALLS, Wis . -- Here are five quick observations from the Chiefs' training camp.

Camp Classic Moment

Personally, it's hard to forget the duel practice session between the Saints and Chiefs in River Falls, Wis., in 1999. It was a war. Mike Ditka brought in a feisty group of Saints. Gunther Cunninghan, in his first year as head coach, had his players whipped to a frenzy. Chiefs offensive lineman Marcus Spears took off his helmet after one altercation and started swinging it at a Saints player. Former Chiefs cornerback Carlton Gray took a late cheap shot on Saints receiver Keith Poole. The Saints had their varied cheap shots. As the scrimmage concluded, both squads of 80-plus players assembled at the end of one field and were ready to rumble. Ditka said enough was enough and ended the practices early and got everyone on the team bus. Had he not, it might have been the biggest NFL fight ever witnessed. — John Clayton

1. Trent Green's accuracy is uncanny. Early in camp, it makes the offense look a little uneasy. Green throws to the spot where the receivers are supposed to arrive. Because they aren't as fast as the Rams receivers, occasionally the passes are incomplete. Sideline observers note how good Green is throwing those out passes to the sidelines.

2. Talented former Chargers second-rounder Mikhael Ricks may have finally found an offense that can exploit his talents. The Chiefs have moved Ricks, who is 6-foot-5, 242 pounds, to tight end and line him up in the slot on the other side of Tony Gonzalez in four-receiver sets. Ricks, once Ryan Leaf's favorite receiver, is fast and has great hands.

3. The sleeper receiver on the Chiefs is 5-foot-6 J.J. Moses, an undrafted rookie from Iowa State. It may be a lot to ask but Moses has the potential to be the Chiefs version of Az-Zahir Hakim.

4. The best battle in camp may be at middle linebacker. Marvcus Patton is an invincible, smart quarterback of the defense. Backup Mike Maslowski is a bigger version of London Fletcher. Maslowski makes plays. Stay tuned.

5. The Chiefs defensive ends are better than people realize. Eric Hicks is a legitimate Pro Bowler. Duane Clemons is a talented pass-rusher who has decent run-stopping skills on the right side.
