Mike LaFleur had plenty to say about Arizona's offense after Sunday's 31-7 home loss to the Seattle Seahawks. What he did not offer was much of an explanation for Marvin Harrison Jr.'s continued disappearance.

The third-year receiver saw just two targets and was on the field for roughly two-thirds of the offensive snaps, leaving him with one catch on five targets through two games. Asked what went into that, LaFleur deflected toward the broader failure.

“I wouldn't look into too much, obviously Trey had some, but I wouldn't look into too much of anything right now,” LaFleur said in an interview with Azcentral Sports reporter Theo Mackie. “Because we didn't throw the ball for crap anyway. Schematically, it wasn't good.”

When pressed that Harrison's snap count was a coaching decision likely made before kickoff, LaFleur pointed to personnel groupings. “I think some of it was obviously being in 13 big. So you only end up having one receiver in there,” he said. “We were in what we call 13 Z, and that's where Mike's our receiver in that. When we're in 13 X, which we had a couple snaps of that, Marv's our receiver in that.”

That answer leaves an obvious question hanging. If the Cardinals are leaning heavily on three-tight-end sets, they are choosing Michael Wilson over Harrison as the lone receiver in their primary version of it.

LaFleur insisted he is not worried about Harrison specifically. “Not concerned, no. I'm concerned with obviously our execution on offense today,” he said. “But I think it's all stuff that we know we can do better, we know we can coach it better and we have a better standard than that.”

The numbers back up the frustration with the passing game. Jacoby Brissett completed 17 of 28 passes for just 95 yards, a touchdown and an interception, and Arizona's longest completion of the day went for nine yards. The Cardinals managed 151 total yards and 10 first downs, with their only score coming on a two-yard pass to Trey McBride early in the second quarter.

Seattle, meanwhile, found explosive plays with ease. Drew Lock threw three touchdowns to Jaxon Smith-Njigba, including an 82-yarder on the game's opening drive.

Arizona falls to 1-1 and visits San Francisco next Sunday.
