Position-by-position look at Arizona’s roster as the season opener approaches.

Steve Keim has no hobbies, but he is a tinkerer. In his first four seasons as Cardinals general manager, Keim made 819 roster moves, including a high of 227 in 2016.

The Cardinals established their first 53-man roster of the year on Saturday, and then made alterations over the next three days. Andy Lee replaced Matt Wile as punter, running back T.J. Logan was placed on injured reserve, and on Tuesday, veteran guard Alex Boone agreed to terms on a one-year deal.

As the season progresses, Keim will continue to churn the last few spots on the roster to deal with injuries and perhaps find a productive player or two.

The roster for the regular season opener in Detroit on Sunday (10 a.m. MST), however, is fairly set. Here’s a position-by-position look at it.

Quarterbacks (3)

HERE – Carson Palmer, Drew Stanton, Blaine Gabbert. GONE – Trevor Knight. PRACTICE SQUAD – None. ANALYSIS – There were no surprises. As long as Palmer is healthy, Stanton will be the No. 2, and Gabbert will be inactive on game days. If Palmer is injured, Stanton and Gabbert move up a peg.

An obvious future starter is not on the roster, but having two backups with experience is beneficial.

Running backs (4)

HERE – David Johnson, Kerwynn Williams, Andre Ellington, Elijhaa Penny, T.J. Logan (injured reserve, eligible to return). GONE – Chris Johnson. PRACTICE SQUAD – James Summers.

ANALYSIS – There is a nice mixture of skills here. David Johnson is as versatile as any back in the NFL. Williams is a productive runner and returns both punts and kicks. He is productive in the wildcat formation. Blitz pickup and receiving are not Williams’ strengths. As a receiver, Ellington’s skills are similar to Johnson’s, which means the Cardinals don’t have to ditch the entire game plan if Johnson goes out.

Penny is a bruiser who can also play fullback. Logan could return after Week 8.

Tight ends (3)

HERE – Jermaine Gresham, Troy Niklas, Ifeanyi Momah.

GONE – Gerald Christian, Hakeem Valles.

PRACTICE SQUAD – Ricky SealsJones.

ANALYSIS – The Cardinals know what they have with Gresham. He’s a good blocker and Palmer trusts him as a receiver. They know what they have with Momah. He’s a good receiver and a weak blocker. What they don’t know is what they have with Niklas. He has the size (6-feet-6-inches, 270 pounds) and athleticism to be an exceptional player.

He hasn’t been able to stay healthy, however. If he does this season, the Cardinals will be fine at this spot.

Receivers (6)

HERE – Larry Fitzgerald, Jaron Brown, John Brown, J.J. Nelson, Brittan Golden, Chad Williams.

GONE – Aaron Dobson, Krishawn Hogan, Chris Hubert.

PRACTICE SQUAD – Carlton Agudosi.

ANALYSIS – The only surprise among this group is Jaron Brown’s speedy recovery from ACL surgery. This position group will be fine if John Brown has recovered from the physical maladies that sapped his talents a year ago. If he continues to struggle, the Cardinals’ deep passing game might take another year’s hiatus.

Offensive line (10)

HERE – D.J. Humphries, Mike Iupati, A.Q. Shipley, Evan Boehm, Jared Veldheer, John Wetzel, Daniel Munyer, Will Holden, Ulrick John, Alex Boone.

GONE -- Cole Toner, Kaleb Jones, Jonathan McLaughlin, Givens Price.

PRACTICE SQUAD – Dorian Johnson.

ANALYSIS – The big surprise on the initial roster was Munyer making the team over Cole Toner, who is now with the Bengals. Munyer was consistent throughout training camp, coach Bruce Arians said, and showed the athletic ability required to occasionally move outside and block blitzing safeties.

Iupati and Veldheer are the fourthand sixth-highest paid players on the team. They need to play up to that standard if this group is going to be above average. Boone was added on Tuesday. He brings experience to the lineup.

Defensive line (7)

HERE – Josh Mauro, Corey Peters, Frostee Rucker, Robert Nkemdiche, Xavier Williams, Rodney Gunter, Olsen Pierre.

GONE – Peli Anau, David Moala, Ed Stinson. PRACTICE SQUAD – Pasoni Tasini. ANALYSIS – Overall, this is a tough, mature group that follows its leader, Rucker. Nkemdiche has the talent to be special. We’ll find out this year how much the game means to him.

Inside linebackers (5)

HERE – Deone Bucannon, Karlos Dansby, Haason Reddick, Josh Bynes, Philip Wheeler.

GONE – Zaviar Gooden, Ryan Langford, Tre’Von Johnson.

PRACTICE SQUAD – Scooby Wright.

ANALYSIS – The Cardinals kept one more inside linebacker than usual for a couple of reasons. Bucannon (ankle) hasn’t practiced since the spring and it doesn’t look like he will play in the season opener. Wheeler’s versatility earned him a roster spot. He can play outside linebacker in a pinch.

Wright is a good special teams player and plays well in confined spaces. The more he has to run, however, the more he struggles.

Outside linebackers (3)

HERE – Chandler Jones, Markus Golden, Kareem Martin.

GONE – Alex Bazzi, Cap Capi, Jarvis Jones, Terence Waugh.

PRACTICE SQUAD – Bryson Albright, Obum Gwacham.

ANALYSIS – This is an excellent trio of outside linebackers. Martin played as well as anybody through camp. There isn’t much depth, but Wheeler can play outside. And Reddick could move there in certain packages when Bucannon returns.

Cornerbacks (4)

HERE – Patrick Peterson, Justin Bethel, Brandon Williams, Tramon Williams. GONE – Jarell Carter, Gump Hayes. PRACTICE SQUAD – Ryan Lewis. ANALYSIS – There’s an All-Pro (Peterson), a backup with some age on him (Williams, 34) and two guys who are unproven (Bethel, Brandon Williams).

Bethel played well throughout the preseason, and judging both by performance and body language, seems confident. Brandon Williams played poorly in the first weeks of camp and then improved. Ideally, he would play special teams and learn this season.

Safeties (5)

HERE – Tyvon Branch, Tyrann Mathieu, Antoine Bethea, Budda Baker, Rudy Ford. GONE – Ironhead Gallon. PRACTICE SQUAD – Harlan Miller. ANALYSIS – There’s a nice mixture of experience, intelligence and athleticism at this spot. Branch looked a lot like last year’s starter, Tony Jefferson, in the preseason. That’s a compliment. Mathieu looked healthy again. Bethea and Baker play in nickel and dime packages. Ford showed speed and tackling ability when he was healthy.

Miller is a solid prospect, too.

Specialists (3)

HERE – P Andy Lee, K Phil Dawson, LS Aaron Brewer. GONE – P Matt Wile, P Richie Leone. PRACTICE SQUAD – None. ANALYSIS – A year ago, the Cardinals tried going young at these spots and it didn’t work. Rookie snapper Kam Canaday got the yips and was cut. Punter Drew Butler was replaced. And in the offseason Phil Dawson was signed to replace Chandler Catanzaro.

So now, the Cardinals have a kicker who is 42, a punter who is 35 and a long snapper in his sixth year.

As long as they all stay healthy, it’s a better group. But we all know that ailments seem to accompany age.

NFL notes

» Attorneys for Ezekiel Elliott say the Dallas running back’s six-game suspension over a domestic violence case has been upheld, but he will play the opener because of the timing of the arbitrator’s decision.

Elliott attorney Jeffrey Kessler told the judge near the end of a more than two-hour hearing in federal court Tuesday night that Elliott’s suspension was sustained by arbitrator Harold Henderson.

» The Miami Dolphins’ season opener against the Tampa Bay Buccaneers will not be played in Miami this week, but may be moved to a neutral site because of Hurricane Irma, the NFL said Tuesday.

If the game is not relocated, it will be postponed until November, when the teams share the same bye week. Kickoff had been scheduled for Sunday at 10 a.m. MST, but Irma is forecast to threaten South Florida this weekend.

» The New York Jets have signed wide receiver Jeremy Kerley to a oneyear deal, reuniting with a player who spent his first five NFL seasons with the franchise. With 246 catches, the 28year-old Kerley has the most receptions among the team’s receivers.
