1. Ike Diogu, Arizona State (22.6 ppg, 9.8 rpg)
Whether or not you feel that Diogu should have been the Pac-10 player of the Year or not, you cannot deny that ASU will miss the big man. With Diogu ASU had a chance at a middle of the Pac-10 finish. Without him ninth place will be a success. His loss cripples the Sun Devils.
2. Nate Robinson, Washington
The Huskies can replace Robinson's numbers but can they replace his heart? He was the heart and soul of the Huskies. He was their fire. They will need the likes of Brandon Roy and Bobby Jones to take up the slack in the leadership department.
3. Salim Stoudamire, Arizona
Some will argue the Wildcats will have a harder time replaceing Channing Frye, but when the Cats needed a bucket in crunch time it was Stoudamire nailing the game winner. Their recent shooting woes show just how important he was to the Wildcats.
4. David Lucas, Oregon State
The Beavers are playing well this season but they lack the star power that Lucas brought. Lucas led the team in scoring and rebounding last season, but it is his leadership that they will really miss. The Beavers have a good win against UCLA bug in losses to Tennessee Tech and Fresno State they really could have used the former walk-on.
5. Channing Frye, Arizona
Although Stoudamire was the shooter, Frye was a force in the middle. The Cats are trying to replace his numbers with the likes of Kirk Walters, Mohamed Tangara, Bret Brielmaier and Isaiah Fox. So far the four have been hard pressed to equal what Frye brought to the paint.
6. Tre Simmons, Washington
Robinson was the heart and soul, but Simmons was important as well. Teammates called him "Tre Murder" for his ability to kill the competition. Simmons made a number of big baskets and big times. The Huskies have some talented replacements, but can they be as clutch as Simmons?
7. Thomas Kelati, Washington State
Kelati was one of two Cougars who averaged double figures in scoring last year. Not that a high powered offense is something Washington State is known for, but Kelati was a genuine scoring threat. They will use a number of players to try and make up for some of the scoring, but the real strategy is for the Cougars to bore their opponents.
8. Dijon Thompson, UCLA
This one has not hurt as much as some assumed. With Cedric Bozeman adjusting to the wing and some of the young players faring well inside, the Bruins have found life after Dijon. Still, Thompson could play the two, three and the four spots and was a good scorer for the Bruins, as well as a key senior leader.
9. Rob Little, Stanford
The big man in the middle was a space eater. The Cardinal do not have a player like that, instead going with more athletic inside players. His strength and size made him a tough match-up, especially for more athletic Pac-10 big men.
10. Marquise Kately, California
Kately's numbers were not staggering, but his departure was more sudden than most. The Bears thought they'd have Kately and Dominic McGuire on the wing, but now must go with smaller players. McGuire transferred, which was a shock enough, but Kately left the team for personal reasons late in the process. Kately could score and defend, and while Omar Wilkes has done a nice job, it remains to be seen if they can overcome the loss of two talented wings.
Others who will be missed: UW Will Conroy (9.4 ppg, 6.6 apg), Cal Dominic McGuire (7.2 ppg, 4.9 rpg), USC Jeff McMillan (9.6 ppg, 6.9 rpg), ASU Steve Moore (12.2 ppg, 2.3 apg), WSU Jeff Varem (10.5, 7.8)
