Three things: Chiefs vs. Cardinals

Here are three things to watch in Kansas City’s preseason opener against visiting Arizona on Friday. Kickoff is set for 8 p.m. ET.

1. The ACL Club: Safety Eric Berry, running back Jamaal Charles and tight end Tony Moeaki will all play. They all suffered torn ACLs in their knees last September. Don’t expect any of them to play extensively in this game, but it will be interesting to see them in action.

2. The quarterbacks: Starter Matt Cassel is under a lot of scrutiny. Every outing is important, no matter if he just plays a series or two against the Cardinals. Also, Brady Quinn and Ricky Stanzi are in a battle to be the backup, so this is a critical game for both.

3. The past two first-round picks: Receiver Jon Baldwin, the No. 26 overall pick in 2011, and nose tackle Dontari Poe, the No. 1 pick in 2012, have been closely watched in camp. Baldwin has been terrific and a lot in expected from him. Also, this is Poe’s first game action. The Chiefs are going to want to see him show he belongs.
