A few things struck me. First, why does everyone (or almost everyone) assume Heild could only start for Pledger. I think he could start over Cam just as easily as Pledger.
Second, someone said Cam hasn't doen much. I disagree. Cam has started in the Big XII as a freshman and sophomore. That is a big accomplishment. He is the only player on the team that started as a true freshman. Cam has not been an All-Big XII player but he has been a consistent contributor. When the Texas high school coach said he could start as a true freshman, he was correct.
Third, if Heild can effectively be a 6th or 7th starter (regardless of when he enters the game), OU should be pretty good. Assume that Pledger, Cam and Heild all have similar levels of talent and all play about 26.66 minutes a game. That would be a really good thing. Presumably it offers more scoring but even more importantly it mandates that players don't take off a possession on the defensive end. When there is a guy on the bench that is rested and capable, you better play defense or someone is headed to the scorer's table.
Fourth, I doubt Cousins starts but I hope he plays 10-15 minutes a game and more in some of the non-conference games. OU has to have a pg ready for next season so OU needs him to get some experience. The reason I doubt he starts is Grooms has three years of college experience, including a full season in the Big XII. He was quite good with the exception of his shooting. A slight improvement in his shooting (which I am hoping happens) will make it very difficult to put him on the bench.
Finally, if OU has an 8 man rotation of Pledger, Osby, Fitzgerald, Clark, Grooms, M'Baye, Heild and Cousins and all 8 are arguably talented enough to start in the Big XII, OU should be a solid team that makes the NCAA Tournament. OU will have Arent, Bennett, Neal and Hornbeak behind that 8 man rotation. We know Neal has shown some ability and at a minimum can contirbute in a limited role. Arent can at least give OU a big body if foul trouble becomes a huge factor (and it really shouldn't this season with Fitzgerald, M'Baye and Osby). Hopefully Bennet and Hornbeak are capable players.
