Questions, thoughts on Cardinals' hires

A few thoughts after the Arizona Cardinals announced Todd Bowles' hiring as defensive coordinator, Harold Goodwin's hiring as offensive coordinator and Tom Moore's hiring as assistant head coach/offense ...

What I like: The Cardinals appear to be committing to their offensive line, an area that was too frequently neglected even though former line coach Russ Grimm came to Arizona with a stellar reputation. New head coach Bruce Arians will call the offensive plays. Goodwin played on the offensive line at Michigan two decades ago and coached the position with the Indianapolis Colts last season. New general manager Steve Keim also played offensive line in college. Arizona has also added a strong veteran presence on its staff through Moore, who has been coaching in the NFL since the 1970s and spent more than a decade with Peyton Manning in Indianapolis.

What I'm not sure about: What can Moore contribute at age 74? What, if anything, will the Cardinals lose on defense after hiring Bowles and pushing out Ray Horton, who finally had the defense playing at a high level? How much of the scheme will Bowles change? The Bowles hiring has been rumored and reported for some time. It'll be interested to hear him provide a general framework for his plans. Some players such as Darnell Dockett might fit better in more of a 4-3 scheme. How much will Bowles want to change?

What I'm guarding against: Dismissing every Cardinals move as meaningless until the team upgrades its quarterback situation. These coaching hires matter a great deal.
