SAN JOSE -- David Fales displayed his patented accuracy and seemed to leave a good impression on the nearly three dozen scouts -- including Oakland Raiders general manager Reggie McKenzie -- that attended San Jose State's pro timing day Wednesday.
Fales was on target with 52 of his 53 passes during a throwing script organized by former Spartans coach Terry Shea, with whom Fales has been training. Only five of his passes were incomplete -- four were drops by receivers and one was an overthrown pass on a deep post.
"I thought he had a good day," McKenzie said. "Shea put him through just about every possible situation, every possible throw that he would have to make and what he displayed is he can make all the throws. I thought he did a good job showing himself. A lot of scouts were here to see it. It was good for him, good for him."
The biggest question dogging Fales has been his arm strength, and he seemed to have a little extra life on his throws.
"Everyone's going to be a critic and has to analyze something," Fales said. "I know what I need to work on and my strengths and weaknesses. I'll always be working on everything."
One of the incompletions was a go route that sailed 60-65 yards in the air but went off the hands of receiver Chandler Jones, who seemed surprised by how far the ball traveled.
"I definitely can tell he's been working," Jones said of Fales. "He's got a lot more zip on it. The ball's really getting there."
There were 35 scouts from 25 NFL teams in attendance. The 49ers were represented by three scouts, plus quarterbacks coach Geep Chryst. Kansas City Chiefs quarterback Alex Smith, who works out at San Jose State during the offseason, also was on hand and watched Fales' session.
Fales and Smith threw together a little bit last offseason and will work out together as Fales prepares for May's NFL Draft.
"I'm really looking forward to that," Fales said. "When you get to train with someone who's been around the league, it's awesome."
Jones may have significantly boosted his own stock when he posted an unofficial time of 4.33 seconds in the 40-yard dash -- a mark that would've tied for the top time among receivers at the NFL combine.
"It definitely shows that I can go out there and run and blow by guys," said Jones, who wasn't invited to the combine.
Fellow wide receiver Noel Grigsby was hoping to show scouts that he's a prospect again after missing the final 10 games of his season with a torn meniscus in his right knee that required surgery. He had the day's best marks in the vertical jump at 37¿1/2 inches and long jump at 10.1 feet. His best unofficial 40 time was 4.56, and he showed off reliable hands while catching passes from Fales.
"I came out here and reached most of my goals," said Grigsby, who estimated he's about 85-90 percent healthy. "I'm just happy to be back out here one more time at Spartan Stadium."
Bene Benwikere, who impressed scouts at the combine with the second-best vertical jump among defensive backs, only re-tested in the 40-yard dash but didn't improve on the 4.63 he ran last month. The versatile defender -- he's played corner, safety and nickel -- said he's heard he could be drafted as high as the third round.
Linebacker Keith Smith's 40-yard dash times were disappointing. He was clocked at 4.91 on his first try, then didn't break five seconds on his next attempt.
"I didn't run as fast as I wanted to but like I've been saying, I've never really been blazing fast so it's not the part of my game I'm too worried about," Smith said. "I felt like I did good in the position drills."
Offensive lineman Ryan Jones and Nicholas Kaspar had mixed review days. Jones only recorded 17 repetitions on the bench press, but managed a good time of 4.87 on the 40. Kaspar crushed 30 reps on the bench, but both attempts at the 40 were clocked at more than 5.5 seconds.
