COLUMBUS, Ohio (WCMH) — After Marvin Harrison Jr. caught his second touchdown pass on Sunday for Arizona, Ohio State head coach Ryan Day knew that this was just the beginning of his success in the NFL.

“Marvin Harrison is a wonderful player,” Day said. “He’s just such a pro. He’s going to translate very well in that league.

The former Buckeyes wide receiver had four catches for 130 yards, including touchdown receptions of 23 yards and 60 yards from quarterback Kyler Murray, all in the first quarter of Sunday’s 41-10 win over the Rams. In fact, he’s the first NFL rookie to put up those kinds of numbers in the opening quarter of a game since his dad, Marvin Sr., did it in his first year with the Indianapolis Colts in 1996.

“Looked to me like some of those were broken plays. I thought the first one was a really great throw and a great catch at the back of the endzone,” Day said. I don’t know how he hung onto that one. But a really nice throw. He’s a great route runner.”

For Harrison’s part, it was a step up from his NFL debut in week 1 when the first-round draft pick managed to record only four yards on one reception against the Bills.

“You can never get too high. Never get too low. Last week, I knew I couldn’t get too low. This week, I’m not going to get too high on a successful day. So I just try to approach each game with the same mindset. Have the same preparation, same routine, no matter how the results are,” Harrison said after his Week 2 performance. “In the end, I’ve never had any lack of confidence in myself or the rest of the team. I continue to get better each and every week and continue to grow.”

Day also had praise for Houston quarterback C.J. Stroud after a 260-yard passing performance against the Bears on Sunday, which included a 28-yard touchdown throw to Nico Collins in the second quarter to give the Texans a 2-0 record.

“I did text him after the game. Just proud of the way he’s handled himself. The way he’s endeared himself to that organization. The way that he’s built hope,” Day said. “The way guys are rallying around him. The way he’s playing.”

Over the weekend, the former Ohio State QB broke a record previously held by Patrick Mahomes for the most passing yards (3,016) through a player’s first ten career home games, including the playoffs.

“Just couldn’t be prouder of the way he’s going about his business on a day-to-day basis,” Day said. “He’s got a lot of people here pulling for him.”
