But it was Robert Lewis who caught the attention of his teammates.
"Robert's been ballin' man," senior quarterback Connor Halliday said. "He's another kid who's put in a lot of work. He came in here at like 148 pounds … he's gained some weight and nobody can catch him out there, he's that fast. He's playing with some confidence which is good to see."
Lewis, who redshirted last season, enters spring now listed at 160 pounds.
Halliday said Lewis was a standout player during the individual workouts he and the receivers participated in three times a week throughout the winter.
Lewis said he's enhanced his quickness during the offseason through morning workouts and speed training with strength and conditioning coach Jason Loscalzo.
"He's been good," coach Mike Leach said. "He's explosive, he's decisive and he's made some pretty exciting plays both of the last two days. Now he needs to keep it up."
Of those explosive plays was a punt return for a touchdown during Saturday's drills when the speedy receiver juked a couple defenders and then gave them an excellent view of the number 15 on the back if his jersey as he ran in for the score.
"Punt returning, I'm feeling way more comfortable," Lewis said. "When I first got out here the punts were real high, different from high school. After you do it a long time you get more comfortable so I feel good back there."
At quarterback, Luke Falk saw plenty of action in both 7-on-7 drills and the team scrimmage. He completed 12 of his 17 attempts, connecting three times with WRs Vince Mayle and Kristoff Williams.
"It was a good learning day," Falk said. "It was good to get out there with the 1s and 2s, the guys around me did a good job of helping me get through it. I thought I had a few positives, a few low points today but it was a good learning day."
DURING THE SCRIMMAGE, Falk went 7 of 15 with one touchdown and zero interceptions. On the touchdown, he floated a deep ball up to Mayle in the back corner of the end zone and the 6-foot-3 receiver had no trouble going up over two defenders to bring it down.
"(Falk) did pretty good, his mind was swimming a bit but he threw the ball good," Leach said.
Leach said he plans to alternate Falk and backup quarterback Tyler Bruggman on a day-to-day basis in order to adequately evaluate each of them.
Falk was also "sacked" once in scrimmage by Ivan McLennan.
Halliday had his share of highlight moments as well, going 9 of 18 in 7-on-7s and 8 of 17 with two touchdowns in the scrimmage. On his first touchdown throw, he found Kristoff Williams on a screen pass. Williams displayed some nifty moves en route to the end zone. Halliday's second score was a quick dart toward the corner of the end zone into the hands of Rickey Galvin.
The secondary wasn't quiet Saturday morning, though. Redshirt freshman cornerback Charleston White managed to outmuscle Dom Williams for an interception on a pass from Halliday. But the play of the defensive play on the practice from freshman CB Marcellus Pippins, who soared over Dom Williams to deflect a deep sideline pass from Halliday, prompting the defensive to erupt with cheers for the young corner.
After practice Leach was impressed with the play of both his freshmen defensive backs.
"They're both quick guys," Leach said. "I think that's been good. Pippins can jump higher than you'd think and Charleston's got really long arms so both of them are kind of deceptive. They've got you a little better covered than it looks based on their athleticism."
On special teams, Pippins turned in another impressive day starting with his first punt return of the drill. Pippins made one move then kicked it into second gear down the sideline for a score.
Others fielding punts were WRs Sebastian LaRue and Brett Bartolone, along with RB Jamal Morrow.
Here are the Cougs' starting units on Day Two:
RB—Theron West and Teondray Caldwell
X, H, Y, and Z receivers—multiple players
C—Sam Flor and Riley Sorenson
CB—Daquawn Brown and Charleston White
S—Taylor Taliulu and Isaac Doston
Running with the 2s on defense on Day Two:
CB—Tracy Clark and Marcellus Pippins
S—Darius Lemora and Beau Glover
"I transitioned to H," he said. "I was playing Y last fall and spring but I felt more comfortable with H and I'm just trying to get with the routes and the option routes."
Leach also noticed improved play in Mayle's game thus far, saying he's more polished on his routes, in better shape and more decisive.
Joining them today was WR Isiah Myers who began the day on the exercise bike before working out with Marks and O'Connell.
