It's easy to be impressed by players running around at spring practice in their "underwear" – the Huskies staff's denotation of being out of pads.
Underwear, pajamas or in plain long-johns, it wouldn't matter – running backs Jesse Callier and Deontae Cooper, two of the four early enrollees at the UW from high school, are fast, powerful and bring a dimension not often seen around Husky Stadium other than from Chris Polk.
Like they did Tuesday, Callier and Cooper took turns with the second-team offense, reading their blockers correctly, turning the corner, running through a couple of tackles and fending off ball-strippers en route to long-gaining runs. And they did it in one big swoop, in a big hurry.
"They're very natural at what they do," UW running backs coach Joel Thomas said. "That's why we recruited the heck out of them, and fought off guys trying to get them late, because we felt they could help our program with the natural ability they have."
If there's only one thing to have learned in Steve Sarkisian's 16 months as coach, it's that he's not afraid to open up positions for young guys to compete for.
Polk (shoulder) won't be a spring-camp participant. On Tuesday, sophomore Demitrius Bronson didn't do himself any favors by putting the ball on the turf twice for turnovers.
On both days, arguably the two most impressive ball-carriers out of pads have been Callier and Cooper.
Callier is smaller with a better burst, but runs with power. He's 5-foot-10 and 187 pounds.
Cooper could end up being a 25-carry running back down the line. He's got the great balance with swiveling hips. He's 6-foot and 191 pounds.
"They fit great with the group," Thomas said. "It's a nice, new, fresh beginning for these two. And they didn't come here to watch ball, they came here to compete. Obviously it's two days, and when we're in pads, then all of a sudden some of those days, it might seem hard to get out there. We'll see."
• Day 2 for basketball-adding-football standout Clarence Trent went better than Tuesday. He even went toe-to-toe with left tackle Senio Kelemete during a quarterback-rushing drill where it got a little heated.
Kelemete, arguably the meanest guy on the UW's starting offensive line, grabbed Trent's' facemask and pushed him back to the east end zone.
Trent didn't care for it much. After the incident was over, he jogged over to the quarterback-dummy and tapped on it, signaling he had found his target.
By all accounts, Trent is a ways away from being a valuable contributor, even though in the absence of a few other defensive ends, he's been seeing action with the No. 2 defense.
But UW defensive coordinator Nick Holt certainly gave Trent credit for a great deal of improvement over the first day.
"It's way, way, way early right now (to know about Trent). He hasn't played in four or five years," Holt said. "And right now at a tempo, a lot of things are happening all at once. He got better his second day. Hopefully he keeps on growing."
NOTES: Wilson High product Desmond Trufant (groin) continued to run up and down the sideline, this time at a little brisker pace than Tuesday, testing out his sore groin. He said he hopes to return sometime during the camp. … Former Seahawks coach Jim Mora Jr. hung around campus Thursday, attending a few meetings and spending time at practice. Mora is expected to do some broadcast work for the NFL Network and Fox Sports Network. … Former UW players Darrion Jones, Terrence Thomas and Daniel Teo-Nesheim were present for the two-hour session Thursday. … Also around was Lakes High's Zach Banner, who eagerly watched many of the offensive lineman drills. … Best catch of the day? Jordan Polk hauled in a pass in the right flat with one hand without missing a beat. … Practice time Saturday is 1 p.m., and it's open to the public.
