Marvin Harrison Jr. scored his fourth touchdown in as many games on Sunday, a fourth-down pitch-and-catch between the rookie and quarterback Kyler Murray on the first drive of the game.

It was a fast start. But Harrison's production didn't keep up, with the rookie finishing with five receptions for 45 yards to go along with the score in the Cardinals' loss to the Commanders.

"Not enough, obviously," Harrison said. "When you get blown out, 42-14, obviously I did not do enough to help the team win."

Jonathan Gannon disagreed with that statement.

"Marv, I thought, actually played his best game," the coach said on Monday. "I thought he launched really well off the line of scrimmage. I thought his route depth and his execution to detail, his routes were really good. I thought he won a bunch of one-on-ones."

Harrison's touchdown was not only a nice reception with a defender by his hip, but he tied the Vikings' Justin Jefferson as the league leader with four receiving touchdowns. He is the first Cardinals rookie since Steve Lach in 1942 as the only first-year players with at least four touchdowns in their first four games. Plus, the toss was the 100th career passing touchdown for Murray.

But it doesn't erase the inability of the offense to sustain success beyond the first quarter. Offensive coordinator Drew Petzing has scripted four flawless starts for the Cardinals offense, scoring on their first drive in every game this year.

After that, the lack of production in the second half came back to haunt them.

"I think just player execution because at the end of the day, that's what it comes down to," Harrison said. "It's 11-on-11. You've got to win your one-on-one as a player in run game and pass games. That's really what it comes down to."

Similar to Week 1 against Buffalo Bills, Harrison recognized Washington Commanders began to play more cloud coverage on his side of field. It showed in his production; Harrison went from late in first quarter to late third quarter without target.

"When we're doing good, you feel that," Murray said. "You feel like 'OK.' The playmakers are making plays and everything's flowing.' But when it's stagnant and you're going three-and-out ... you can't get rhythm and you're off field; everybody's stats are going look like that."

Gannon said there were moments when Harrison was open but ball didn't find him; both coach and quarterback agree ball needs be No.18's hands.

It's all part process as Murray-Harrison develop chemistry; hope is chemistry extends beyond first quarter.

"I'm definitely getting more comfortable out there; guess that's positive (Sunday) for me," Harrison said."Other than that I've got continue do my job help team win."

MCBRIDE "LOOKING GOOD"

Gannon wouldn't say what tight end Trey McBride would do this week after missing Sunday's game with concussion but added McBride was "looking good" recovery; coach also said team had couple more days evaluate if any player -- specifically defensive lineman Darius Robinson -- would return practice this week as rehabs IR.
