Notes from around the NFC West on a Friday night in St. Louis:

Randy Moss' second news conference since joining the San Francisco 49ers is worth a look on the team's website. He appears to be soaking up the experience after a year out of the game. Moss lauded head coach Jim Harbaugh and receivers coach Johnny Morton by name. Back when the 49ers ran him through a tryout, Moss was surprised to discover Harbaugh would be the one throwing passes to him. Moss is a football junkie. So is Harbaugh or just about any player with enough love for the game to grind away as a coach following retirement.

Word that receiver Michael Crabtree left 49ers practice with an potential ankle injury will generate groans. Crabtree has missed only one regular-season game to injury during his three-year career, but injuries have sidelined him for large chunks of previous training camps. No word yet on the severity of this injury. Matt Barrows of the Sacramento Bee thought Crabtree appeared fine while leaving the field after practice.

49ers pass-rusher Aldon Smith, stabbed at a party earlier this offseason, is apparently OK.

Kent Somers' report from Arizona Cardinals' camp singles out rookie receivers LaRon Byrd and Michael Floyd for making impressive plays. Byrd stood out a couple times during the team's three-day minicamp last month. How does a 6-foot-4, 220-pound receiver from the University of Miami go undrafted? By struggling under a new coaching staff as a senior and falling out of the receiving rotation at times. Byrd was highly recruited. He's obviously talented physically. Perhaps the Cardinals have found a bargain. Obligatory disclaimer: It's early.

The Seattle Seahawks open camp Saturday. They've moved their practice time to 10:30 a.m. PT. The focus should be on football for the most part. The team has no lingering contract issues to worry about now that Chris Clemons is under contract. Marshawn Lynch's status with the NFL following a DUI arrest stands as the most significant off-field issue regarding the team. Russell Wilson's performance in the team's three-man quarterback competition is the subject I'm most interested in following early in camp.
