It's simple, if he goes to UW he'll have a great college experiencing shitting all over this shit conference and going to the playoffs. If he goes to Oregon, somebody on UW's defense will break him in half. You can either play against the best defense in practice every day and be challenged to get better or you can plateau at Oregon and play against UW's defense every year in live games and get your ass kicked with lesser quarterbacks throwing you the ball. From this point on, you do not want to playing in the the North division for any team besides UW. At Oregon, you'll be retard fighting the other North teams for second place. The choice is yours. But it's really not that difficult.

UW has a real dynasty
They bout to.
Why would UW be better next year?
Because statistically Washington's defense has improved four years in row regardless of losing numerous big-time defensive players to the NFL over the years. Overall, UW's defense will be deeper and more talented than it's ever been during the Petersen era. There will be zero holes from a talent perspective at any position on defense. UW's biggest weakness on defense has been their pass rush from the edges. RS Sophomores Joe Tryon and Ariel Ngata, RS Freshman Zion Tupuola-Fetui, and true Freshman Laiatu Latu give UW the talent they need to vastly improve that weakness and turn it into a strength.
On offense, UW returns 4 out 5 starters on the offensive line. Former 1st-team All-Conference 6'8 LT Trey Adams returns healthy for his Senior season. 1st-team All-Conference Center Nick Harris returns for his Senior season. RG Jaxson Kirkland was a Freshman All-American last season. He returns for his RS Sophomore season and with another year of physical development under his belt, the 6'7 long-armed behemoth will compete for All-Conference honors. At RT, Jared Hilbers likely gets the nod. The 6'7 soon to be Senior started most of the season at LT for UW while filling in for Trey Adams and there was no noticeable drop off between the two. LG is the only question mark. Last season's starter RS Junior Luke Wattenberg returns but RS Sophomore Henry Bainivalu and RS Freshman Victor Curne are both a threat to beat him out for the starting job.
At QB, UW will experience a major change in QB talent. Browning and Eason are on opposite ends of the spectrum when it comes to college QB talent. It's a massive difference in talent at the most important position on the field.
At RB, Salvon Ahmed looks to replace Myles Gaskin as UW's new primary back. Ahmed needs to improve his decision making but his talent exceeds Gaskin's and he's a homerun threat every time he touches the ball.
All of UW's receivers return from last season along with an infusion of talent from Chris Petersen's best WR class to date: Austin Osborne, Marquis Spiker, and Trey Lowe.
At TE UW returns the best receiving TE in the country, Hunter Bryant, and traditional TE Cade Otton who's a quality blocker and threat in the passing game as well.
On top of all of the returning talent, UW also has a soft non-conference schedule to break in new players at key positions and get everybody dialed in for conference play. UW's conference schedule is also extremely favorable with games against USC, Oregon, Utah, Cal and WSU all being at home. Their toughest game will likely be Stanford on the road and Stanford doesn't have much of a home field advantage with sparse crowds. Out of UW's 12 regular season games, 7 of them will be at home. UW is undefeated at home the past two seasons. Their road games will be at BYU, at Stanford, at Arizona, at Oregon State, and at Colorado. That's probably the easiest road schedule in the conference.
Does that suffice?
