At 6 ft 6 he would have played the 4/PF at a JC. When I walked on/made the team, and was a Mascot at Big Bend Community JC College, the Center/5 was 6 ft 7.5, and the PF/4 was 6 ft 5.
That's par for the course at JC colleges. JC colleges are not like Div 2, Div 1, Mid Major/Power 5, etc, where the 5/center is 6 ft 8.5+, and the PF is 6 ft 7.5+, where generally a 6 ft 6, unless they are Charles Barkely esque, dont generally play the 4/PF, and instead play the 3/SF/3 guard.
The only exceptions to that are the 6 ft 6.5 in Lodwicks, WHEN, IF WSU/a team is undersized, has a hole at the 4/PF spot that they are trying to fill, or if the player is Charles Barkley, Ivory Clark, Jeff Varem like, esque.
WSU has: Vova, Jackson, Tony Miller, Agobidi, Chatfield(6ft 10).
That's 5 deep at 4,5/Center/PF, bigs spots. And the shortest is Tony Miller at about 6 ft 7.5 to 6 ft 8.5.
So there is no hole at the 4. So there is no reason why the 6 ft 6 in new recruit would play the 4 at WSU.
If CJ stays in the Draft, and even if he returns, the new 6 ft 6 in recruit likely plays the 3/SF/3 guard spot, not the 4, no matter if he is listed at 3/4 or pegged as a 4 by outside sources.
Unless Smith or other WSU coaches, etc, say he is going to play the 4, he is going to play the 3.
