Powell is a four-star defensive back out of Upland High, the same prep team as Tyler Hilinski, who is already enrolled at WSU. Powell made 77 total tackles this season and recovered two fumbles, returning one for a touchdown.
Notre Dame made a run at Powell in mid-January by reaching out to him on Twitter. But Powell indicated on Scout.com that he remained solid to WSU. He's been verbally committed to WSU since May.
About a week ago, he tweeted a promising picture on his Twitter account. The caption read "Wazzu" with paw-print icons next to it. The picture consisted of six separate images - the large one of Powell and the other five were smaller pictures of WSU highlights.
Besides WSU, Powell had offers from Colorado, Colorado State, Oregon State, San Jose State, Utah and Washington.
The 6-3, 185-pound wide receiver out of Westmoore High caught 58 passes for 961 yards and 14 touchdowns in 11 games this season, earning him the No. 2 wide receiver ranking in Oklahoma, according to Scout.com.
Green visited WSU in October and pledged in early January over 15 other offers. But Green then got a last-minute offer from an in-state school, Oklahoma, on Tuesday and is visiting there now. He has not withdrawn his commitment to WSU but ESPN and others are predicting he flips to the school in his home state. Green's high school coach Adam Gaylor said new OU offensive coordinator Lincoln Riley made a solid first impression on Green this week.
WSU sent out a release back on Dec. 17, the first day of the mid-year junior college signing period, announcing the signing of Luani -- the four-star safety out of City College of San Francisco (DE Jeremiah Mitchell's signing was also touted in the WSU release). Luani earned the Bay 6 Conference Defensive Player of the Year award this past season in recording 69 total tackles (including six tackles-for-loss), four interceptions, and two forced fumbles.
Luani (6-1, 200) chose WSU over Oregon State, Washington, Illinois and others. He is ranked No. 19 at his position by Scout.com. Luani will have three years to play two for the Cougs.
Mattox, a 6-4, 260-pound defensive end out of Chatsworth, Calif., played on both sides of the ball in high school but he's a d-lineman at the next level. On defense, Mattox made 86 total tackles, including 10 tackles-for-loss. He specialized in putting pressure on the quarterback, totaling 15 sacks and 18 hurries in 12 games this season. He's athletic, carrying the ball three times with a TD for Sierra Canyon High this past season.
The future Cougar defensive lineman flipped his commitment from Oregon State mid-December during his visit to WSU. He lauded the WSU coaching staff in an interview with CF.C and pointed out how the Oregon State coaching transition resulted in communication lapses. It wasn't as if the Cougs just swooped in at the last minute, though. He said WSU had been recruiting him since his sophomore year.
Mattox is rated three stars and the No. 10 defensive end in California by Scout.com. He chose WSU over offers from OSU and Fresno State.
