GLENDALE, Ariz. — Over the past few months, for most of his time as head coach of the Arizona Cardinals, Mike LaFleur has been asked about Jacoby Brissett, his projected starter at quarterback who has held out from practice because he wants a contract that reflects his job title.LaFleur has never said much during these conversations, and Thursday’s first day of training camp was no different — with one exception. LaFleur said Brissett would practice. He did not elaborate when asked if Brissett would take reps with the first-team offense. Asked to describe his QB situation, LaFleur said simply: “I’d describe it as Practice 1 on July 23.”The Cardinals opened camp early because they’re playing Aug. 6 against the Carolina Panthers in the Pro Football Hall of Fame Game in Canton, Ohio. That event, centered around the enshrinement of former star receiver Larry Fitzgerald, may turn out to be the highlight of their season. It’s off to a rough start.Will a scheme change unlock Cardinals wide receiver Marvin Harrison Jr.?Robert Mays and Derrik KlassenThe Cardinals are coming off a 3-14 season, among the worst in their not-so-glorious history. They made a coaching change, discarding Jonathan Gannon for the 39-year-old LaFleur. They drafted running back Jeremiyah Love, a popular pick for NFL Offensive Rookie of the Year. Since then, off-field incidents have flushed away preseason optimism before it’s had a chance to sprout. It’s hard to grow anything in the desert this time of year.This month, the NFL suspended executive Ryan Gold for violating the league’s gambling policy. (His attorney says Gold, the team’s director of college scouting, will appeal.) Right guard Isaiah Adams, a projected starter, was arrested in his native Canada and charged with firearms offenses. (His attorney says Adams is innocent.) Like Brissett, Adams participated in Thursday’s practice.“He’s doing good,” LaFleur said. “I’m not going to comment too much on that.”
