GREEN BAY, Wis. -- First-round pick Kenny Clark posted the sixth-best total on the bench press among defensive linemen at the NFL combine. Second-rounder Jason Spriggs ran the fastest 40-yard dash of all offensive linemen and was third on the bench. Fourth-rounder Dean Lowry tied for the fastest 40 among all defensive linemen over 290 pounds. Only two receivers ran faster 40s than fifth-rounder Trevor Davis.

It’s safe to call the Green Bay Packers' selections pre-draft workout warriors.

But here’s the thing Ted Thompson and the other 31 NFL general managers must figure out: How much should exceptional pro day or combine performances weigh in the overall evaluation?

It’s easy to be blown away by impressive workouts, but Thompson is a veteran talent evaluator who surely can see through a player who simply looks good in shorts and a T-shirt.

“This process is so detailed,” said Packers coach Mike McCarthy, who has sat by Thompson’s side for every draft since 2006. “I can’t say enough about the personnel staff particularly, just the knowledge ... not only getting the board set but just the class evaluation, looking at the board vertically, horizontally, by position, breaking out into groups. We felt very good about the way our board was stacked, and we trusted it.”

It’s easy to be intrigued the most by a first-round pick, and all eyes no doubt will be on Clark. The Packers will expect him to contribute immediately, perhaps even as a starter on the defensive line.

But perhaps the more intriguing prospects came later in the draft in part because of what they did in their workouts.

Packers director of football operations Eliot Wolf raved about Lowry’s combination of athletic ability, and sure enough, Lowry tied first-round pick Robert Nkemdiche for the fastest 40 time (4.87 seconds) of any defensive lineman over 290 pounds at the combine. Wolf also mentioned Lowry’s power, and that showed when he put up 30 reps of 225 pounds on the bench press, the fourth-best total among all defensive linemen.

“Over 30-inch vertical [and] 30 [reps] on the bench,” Wolf said.

But it wasn’t just workout numbers that impressed him.

“Disruptive [against the] run and pass,” Wolf said. “Lined up all over the line -- outside, inside. Just a solid player for Northwestern. He's really versatile. Can play inside at the 3-technique, outside at the 5. Probably could stand up some, but we do see him as a defensive lineman.”

The only skill-position player Thompson picked was one of the fastest in the draft. Davis’ 40 time of 4.42 seconds was bettered by only two receivers at the combine. One of them, Will Fuller, was a first-round pick. Wolf said the Packers actually timed Davis in the mid-4.3 range.

Wolf said Davis’ speed was one of the main attractions, but something else stood out when the Packers watched him work out.

“His pro day was unbelievably good with the ball skills,” Wolf said. “His tracking ability down the field, effortless catching, very smooth.”

Clark’s strength -- he put up 29 reps on the 225-pound bench press -- should help him in the trenches. Meanwhile, linebackers Kyler Fackrell (4.71 40-yard dash) and Blake Martinez (4.72) should have enough speed to drop into coverage when necessary.

Still, there's no guarantee impressive workout performances will translate to NFL production.

“A lot of work obviously goes into this for each and every club,” McCarthy said. “We feel very good about where we are so far in the player acquisition phase. And then frankly, this particular season, watching it all come together and really the way the board fell, we just stuck to our guns.”
