We have Spangler, Cousins, Woodard, and Lattin this year! We didn't know Woodard would be good that year (heck, he still can't buy praise from a lot on this board). Talking about next year right now is fool's play. Who knows? OU may have another person coming in. I could easily see Kruger's system getting OU to 3rd in the Big 12 on system alone (let alone the talent he has brought in).
That's the point, we're talking about improving or taking a step back.
Assuming that experienced players who got significant minutes don't typically improve production a ton...you can hold those guys the same or maybe like 10% on average growth in production per minute.
That way you know what other guys incoming (new players) need to provide.
That's just from a statistical point of view. Then you have to consider things intangible like team cohesiveness, go-to players, and players you can rely on in tight games.
We lose alot of intangibles if Hield leaves. He was the 1st or 2nd vocal leader behind Ryan. We lose team choesiveness if Hield goes. We lose a big reliable player (he wasn't consistent necessarily) but he was a player we could simple give the ball to in the post and he would more times than not get a bucket or draw a foul in Tashawn Thomas.
We lose a 3 point shooter who could get hot in Booker.
Neither James nor Odomes are great 3 point shooters. Buford isnt either.
Cousins put up a good% cuz he took smart shots but his actual form is below avg.
With hield and booker gone, our 3pt shooting may suffer...causing harder lanes for our new athletic guards and current ones (cousins/woodard) to use to create or drive.
We then dont have a real post offensive presence. Maybe spangler gets some post moves but doubtful. His best bet is to perfect the jumper he has in midrange but he goes in and out of hitting that consistently.
If hield goes, from a production standpoint we lose a lot but the dynamics behind the makeup of our team leave much to be desired.
IDK about national rankings but in Big12, if Hield leaves...it definitely puts us behind KU and ISU (if we werent already...prly were) and probably puts us around Baylor who returns a ton of guys and WVU. I guess we could still finish 3rd if Kruger does a great job but I dont envision a very successful season with our offense running through Woodard, Cousins, Buford plus maybe a freshman off the bench in Odomes.
Spangler, Lattin, Manyang will be great role players. Spangler being one of the best "role" players we have ever had. They just aren't going to be guys we can expect point production through a normal set of offense. Spangler gets the majority of his points from opportune moments int he game rather than through a set offensive play except for a few mid range shots in a set a game.
