From the DO article -
(In addition to being down QB1, HC, OC, DC )
On offense, starting running back Wayshawn Parker has already left for Utah, and No. 2 receiver Kris Hutson departed for Arizona.
In place of Mateer at quarterback will be Zevi Eckhaus. The senior transferred from Bryant and played just 19 snaps in his first year with the Cougars. Brown said he’s watched lots of Eckhaus’ Bryant film, saying he “thought he did a good job.”
WSU’s defensive line has also been decimated by the transfer portal. The Cougars have already lost Khalil Laufau and Ansel Din-Mbuh. Meanwhile, leading tackler Taariq Al-Uqdah transferred to archrival Washington less than an hour before Thursday’s press conference.
Kaligis added David Gusta, who’s currently in the portal, won’t be playing due to an ankle injury.
So, yeah.
It’s a LOT more than “just down 3 starters” for the Cougs.
