Denver pregame look

Posted by ESPN.com' s Bill Williamson

DENVER -- Here is a look at some keys for Denver against visiting Dallas tonight:

Ryan Clady: Denver's first-round pick has had a good training camp but he has struggled some against live competition. Houston's Mario Williams ate him up a couple times last week, and in a joint workout with Dallas, the Cowboys' DeMarcus Ware had his way with Clady at times. Clady will start at left tackle for Denver, so this action against quality players will help him.

The defensive line: Denver's defensive line has not had much of a pass rush established yet. It was near nonexistent against Houston and the defense line had difficulty against Dallas' offensive line this week. It is time for Denver to show some pass rush ability. Second-year players Jarvis Moss and Tim Crowder have struggled some in camp. They need to show up tonight.

Matt Prater: Jason Elam's replacement at kicker has been good is training camp. He needs to continue to kick well. He missed a 30 yarder last week, on his first attempt but made his next three field goal attempts. Denver wants to keep Prater, but he has to show he can handle the job.

NOTE: I will be covering the game tonight and will provide updates throughout the evening.
