STANFORD — Jack Richardson took every snap of the Cardinal and White Spring Game as a walk-on quarterback Saturday afternoon at Laird Q. Cagan Stadium.

He walked off the field with a scholarship.

“In fact, Coach Shaw gave me one after the spring game,” Richardson said. “It is official, yeah.”

Stanford coach David Shaw flashed a smile when asked if the 6-foot-5, 202-pound junior out of Salinas deserved a scholarship.

“We’re taking care of Jack,” he said.

Richardson was the only healthy quarterback on the roster during the spring as K.J. Costello (hip) and Davis Mills (knee) sat out with injuries while Keller Chryst plans a transfer to Tennessee.

“I told the guys we’d probably have to do a lot of wind sprints just to condition, because we wouldn’t have been able to really practice without him,” Shaw said.

Apparently taking all of the reps at practice paid off.

Richardson guided the Cardinal (offense) over the White (defense) by a score of 24-16, orchestrating 10-play touchdown drives at the beginning of each half.

He finished 21 of 30 for 178 yards with two touchdowns — and one interception that put a sudden halt to the spring game as cornerback Noah Williams was flung off his feet after a collision with guard Nick Wilson on the sideline.

“We were blowing the whistle and trying to end it, and we had a little unnecessary contact at the end,” Shaw said. “Everybody is healthy, everybody is in pads. It’s not the worst thing in the world.”

Is there a rivalry between the Cardinal and White? The offense and the defense?

“We definitely like to chip at each other a little bit,” running back Cameron Scarlett said. “We spend so much time with each other, we’re all so close that when we get a chance to go against each other we take it pretty personal. I mean, it’s definitely all love, but at the end of the day it’s a rivalry.”

Scarlett ran for 111 yards on 18 carries, including a 22-yard touchdown on the opening drive.

The 6-1, 214-pound senior was the featured back because Heisman Trophy runner-up Bryce Love was kept out of contact drills the entire spring for precautionary reasons.

“Bryce Love, trust me, he’s going to get his fair share,” Shaw said. “But for us to be successful, that ball is going to hit a lot of different hands and we’ve got to anticipate that and be ready to take advantage of those opportunities when they come.”

Eleven different players were targeted by Richardson, with his favorite target wide receiver Connor Wedington.

The 6-foot, 197-pound sophomore caught six balls for 68 yards, including a 15-yard touchdown on the opening drive of the second half.

“I definitely think with all the playmakers that we have it’s going to open up the offense a lot,” Wedington said. “The biggest thing for us is we’ve just got to be selfless.”

The third touchdown came from an unlikely source.

Fullback Houston Heimuli, who powered his way to 41 yards on 12 carries, caught a 5-yard pass in the flat with one hand off a play-action fake and snuck his way inside the pylon.

“Those rugby guys can catch the ball a bunch of different ways,” Shaw said. “He showed his versatility.”

On defense, Andrew Pryts made eight tackles after a shift from safety to inside linebacker, while free safety Ben Edwards also recorded eight tackles and a pass breakup.

“He’s always been known as a big hitter,” Shaw said of Edwards.

Also making a strong impression were cornerbacks Malik Antoine (7 tackles) and Paulson Adebo (5 tackles, 2 pass breakups).

“I don’t even know if you can see his ceiling — it’s extremely high,” Shaw said of Adebo. “He’s got length, he’s got speed, he’s got a great attitude, he’s very physical. The guy makes tackles outside, he can make plays on the ball, he had a couple of pass deflections today. Our aspirations for him are very, very high.”

Love, Costello and Mills weren’t the only players watching from the sidelines. Among others MIA:

• cornerback Alijah Holder;

• inside linebacker Bobby Okereke;

• safeties Frank Buncom and Brandon Simmons;

• center Jesse Burkett;

• running back Trevor Speights.

“It was hard to just be so physical for so many days in a row like we like to be just because of the lack of numbers,” Scarlett said. Related Articles Stanford coach David Shaw on working with Raiders’ Jon Gruden, Saints’ Sean Payton

Limited participation, including only one healthy quarterback, forced the coaching staff to modify practices and scrimmages.

But players were not asked to hold back any punches for the Cardinal and White Spring Game — and it showed.

“I loved how physical it was,” Shaw said. “I told them yesterday, ‘I want us to reach a level we haven’t reached all spring and let’s really get after each other and get physical.’ And I saw that today. It was great. There was a lot of pads popping and guys still popping up. Except for the last play, all taking care of each other. But I felt good.

“It felt like Stanford football.”
