We’ll jump right into things with this in-depth piece of analysis that you won’t find anything else: Paul Richardson is fast. Really fast.

Of course you probably knew that already, but seeing the second-round pick in person backed up what we heard about the receiver after the Seahawks picked him on Friday.

The play that stood out most saw Richardson blow past sixth-round pick Eric Pinkins and catch a 63-yard touchdown pass from Keith Price. Richardson had to slow down a bit to let the ball catch up to him, but even after downshifting, he maintained separation from Pinkins. Richardson also showed good hands, making a few nice catches going to the ground.

A few other highlights from the day:

—Keith Price came to this minicamp with an advantage over some of the other rookies having not only played in a system with similar terminology to Seattle’s (obviously Steve Sarkisian brought to Washington a lot of what he had done under Carroll at USC), and having also gone through workouts with Seahawks coaches. That familiarity showed, with Price looking much more in command (and just better) than tryout QB Zach Zulli.

“The workout he had with us and just being around our coaches a little bit (helped),” Carroll said. “He did a nice job today.

“He’s done well. He’s done really well. He looks like he’s been around. He’s run more similar stuff, he’s got a great advantage over Zach Zulli.”

—Fourth-round pick Cassius Marsh showed some impressive pass-rushing moves, getting into the backfield quickly on several occasions.

“He’s a real natural pass rusher,” Carroll said. “He’s got great stuff already, you can see he’s got really good hands and has a good feel for it. What will be important as we move onward is to figure out where he can best fit in. We’ll be really open to seeing that. Right now he’s kind of playing like Michael Bennett plays.”

—Linebacker Korey Toomer, who is heading into his third season, was one of a handful of non-rookies practicing (players who have not accrued a season of service time because of injuries or because they were on the practice squad, can participate in rookie minicamp), and the former fifth-round pick out of Idaho had a good day, including a leaping interception that he returned for a touchdown. Toomer missed all of last season with a knee injury, but is a player for whom the Seahawks have high hopes if they can keep him healthy.

“Korey looked good today,” Carroll said. “Korey’s had great workouts throughout phase one and phase two. He’s in great shape and he’s very determined. That’s one of the guys it’s really exciting to see him have another chance at it. He really didn’t get started last year, he got hurt, so we’re all pulling for him.

—Offensive lineman Garrett Scott, a sixth-round pick, didn’t practice because he has yet to pass his physical, Carroll said. Receiver Chris Matthews, who was signed out of the CFL, was held out with a sore hamstring.

—Defensive end Bruce Irvin took in a bit of practice from a jet ski, taking a play out of Richard Sherman’s playbook from last year’s rookie minicamp.
