STANFORD — The weather wasn’t expected to cooperate Thursday morning at the Siebel Practice Field, which explains why Stanford purchased a massive tent to keep the turf dry for the 40-yard dash in front of NFL emissaries at the annual pro day on The Farm.

“I guess it was a good investment,” defensive lineman Harrison Phillips said. “It’d be nice for graduation in a couple of months.”

If there’s one person who couldn’t care less what Mother Nature had in store for his latest audition in advance of the NFL Draft on April 26-28, it’s the 6-foot-4, 295-pound behemoth known as “Horrible Harry.”

“I played in Nebraska,” Phillips said. “I played in 100 degree weather, played in inches of snow, so it doesn’t really matter to me. And that’s why any team can pick me and I’ll be able to play wherever we’re at.”

Phillips, who as a redshirt junior led the Cardinal in tackles (103) and sacks (7 ½), left a strong impression at the NFL Combine in Indianapolis, highlighted by the most reps in the bench press at 42.

The pro day was another chance to shine, this time without many of the distractions.

“There’s not the psychological testing and I didn’t have four hours of sleep,” Phillips said. “I was adequately rested, I had a good meal last night, I was hydrated and could come out here and demonstrate my strength, which is playing football.”

One person evaluating talent was the one being judged on the very same field in 1993.

“That field used to be grass,” said 49ers general manager John Lynch, a quarterback turned safety while at Stanford. “Just as Justin Reid and those guys were out there doing their DB drills, I remembered — gosh, that was 25 years ago now.”

“The whole thing is a job interview,” said Reid, who finished second in tackles (99) and led the team in interceptions (5). “My Twitter is a job interview. I know they’re watching everything.”

Also watching Justin Reid, a 6-1, 204-pound safety, was his older brother Eric, drafted 18th overall by the 49ers in 2013, but currently a free agent.

“It was awesome,” the younger brother said. “At the beginning he came out on the field, he was warming me up, he took me through some DB drills. This is what I was looking forward to as a kid, being able to come and train with my brother.”

While not related by blood, he also formed a close kinship with cornerback Quenton Meeks during his three years at Stanford.

Linebacker Peter Kalambayi also represented the defense in the pro day.

“Being here with the boys, it was surreal,” Reid said. “It’s like the last time I get to suit up with these guys wearing the Cardinal red. Lemme tell you, my highlight of the day was seeing Q Meeks run his 40 time [4.49]. I don’t know if you saw on the sideline, I was jumping around more than anybody seeing what he did.”

On offense, Ryan Burns pulled double duty at quarterback and long snapper. He was joined by tight end Dalton Schultz, fullback Daniel Marx, offensive lineman David Bright and long snapper C.J. Keller.

“I felt like I showed them the best version of myself,” said Schultz, one of six Cardinal invited to the combine held three weeks ago. “I had the opportunity to redo bench (press), I thought I attacked that really well. Coming out here running routes with roommate Ryan Burns was super fun. We were talking about it all week. So coming out here and actually being able to go through it and have this pro day, it’s been something I’ve been anxious for.” Related Articles Stanford coach David Shaw on working with Raiders’ Jon Gruden, Saints’ Sean Payton

Now it’s a waiting game until the NFL Draft.

“I’ll be back around here staying in shape,” Schultz said. “Making sure I’m ready to go when my number is called.”

Turns out at least one of his former teammates has an inkling of when that might be.

“I’m curious to see where is Dalton and where is Justin and Quenton and some of these other guys that are coming along,” said Phillips, who keeps track of mock drafts. “So I do see that a lot and I really appreciate when people speak highly of me. … None of it is real in the scheme of things, but it’s nice that somebody appreciates me.”
