CJ Williams was a top 10 WR recruit in the country. He had a better recruiting profile than any WR in UWs history and I think would have been something like 12th highest rated recruit of all time (depending on the site you use).
They have had two 4 star QBs recruits - Mertz and Houston - in their history and just got three of them via transfer or recruit. (people are forgetting Mettauer) plus a bona fide college starter.
Then toss in the WR from OK State who was very productive last year. He has a pretty high floor.
I think people are excited to see skill positions other than RB or TE gain significant depth
