(AP Photo/Matt York) The Arizona Cardinals opening the preseason by hosting the Kansas City Chiefs will satisfy fans by ending a summer without football, but at the end of the day, preseason football lends little evidence of how the team will look come Week 1.Quarterback Carson Palmer taking one series of snaps, after recovering from his second ACL tear, will be significant within itself. Yet, there’s a more significant comeback leading the shortlist of storylines on Saturday night. Former Cardinals kicker Phil Dawson retires Here’s more on that and a few other observations we can glean from in the Cards’ preseason opener.Eric Berry is playing football againGet your tissues ready. Chiefs’ safety Eric Berry will play in a game for the first time since beating Hodgkin’s lymphoma.Fittingly, the Cardinals honored Berry’s battle last year when they played Kansas City.Last Dec #KCvsAZ gm Eric Berry was on every1’s mind as he battled cancer.

Alongside Larry Fitzgerald, rookie J.J. Nelson and his 4.28-second 40-yard dash capabilities could be teamed with John Brown — the second-year receiver is said to have improved greatly since last season — to give Arizona two small but speedy options at Palmer’s disposal. Third-year receiver Jaron Brown, who had 22 receptions for 229 yards last season, could also use the opportunity to catch head coach Bruce Arians’ eye.And the tight end position will likewise be something to watch. Will the inexperienced Ifeanyi Momah and Jermaine Gresham become frequent, reliable targets for Palmer while supplementing blocking package tight end Darren Fells? 0 Comments Share Still, there will be times when a base defensive look will be needed. With Sean Weatherspoon out of the game, Kevin Minter, Glenn Carson and Kenny Demens have a chance to make their move at a position that may cause worry.Time6 p.m. MSTTVABC 15RadioArizona Sports 98.7 Grace expects Greinke trade to have emotional impact The 5: Takeaways from the Coyotes’ introduction of Alex Meruelo Derrick Hall satisfied with D-backs’ buying and selling Top Stories Punters are people tooApparently, punter Dave Zastudil doesn’t have a lock on his job. Bruce Arians indicated that Drew Butler is challenging the 14-year NFL veteran, though it’ll be Zastudil who first can make his case for winning the job on Saturday. The two will alternate preseason games.Offensive line depthBetween starting right tackle Bobby Massie’s DUI arrest that led to a suspension, to the team’s quest to find a capable starting center, there’s a lot of complexity to how the Cardinals’ offensive line looks come the regular season. In any case, depth will provide options and Arizona hopes it has that. Improvement from guard Jonathan Cooper, the team’s 2013 first-round pick, and inspired play from rookie right tackle D.J. Humphries, who earned a not-so-great nickname, would be positive signs.Defensive strengths and weaknessesIt would appear that the Cardinals’ defensive backfield is in fine shape. Patrick Peterson is healthy after battling blood sugar issues last year, and Tyrann Mathieu has recovered well enough to become a playmaker thus far in practices. It’s a deep group, enough to where one wonders if Arians will be more willing to roll with nickel and dime looks (More Deone Bucannon at linebacker, anybody?).
