Well, I have, since before the season started, thought Wague should have been starting and playing until he fouled out. However, like Boulder, I certainly would play Sam before Luke at the 5. I think Sam is a good player that is just athletically outmatched sometimes. I wouldn't start Wague over Sam because Sam isn't any good, I just think with enough minutes, Wague's upside, particularly on defense is higher. Played as much as possible all year, I think Wague would be much better than he is now. But, I like Sam and think he usually plays pretty well.
On Luke. I don't know how Porter sees him. If Luke, or anyone else, thinks he can play on the perimeter defensively, I believe them to be delusional. I like Luke's potential inside. He is soft, but that can sometimes be fixed, with the right mentorship and coaching. I would have liked Porter to tell Luke, his first year in the program, he would need to become a post player, and work around the clock on being a post player, or he would never make it at OU. Let Luke decide whether to "get with the program" or move on. OU needs post players. I think Luke could be a post. But, you can't let the kid run around in practice and games outside the 3 point line and shoot 3 pointers. We don't get to go to practice with Porter (I did once this year) but physical positioning around the rim is a taught skill, as is offensive play around the rim where every shot is guarded. Luke clearly has no idea what he is doing around the rim, and clearly hasn't put in the hours and hours of getting guarded shots to the rim from near the basket. Sure he can hit layups and put backs but that isn't what I am talking about.
For example, Eddie Sutton would have, provided Luke had given him a couple year to do it, made Luke an acceptable or competitive post, IMO. So, I like Luke, and I think he is improving. I trust Godwin in the post more than him at the moment. I would like to see Luke stay, I just hope he comes to the realization of what he needs to do to maximize his potential as a basketball player. EPL might want to be a cornerback, but his only future in football is on the line of scrimmage. And, practicing at cornerback every day will not make him a good lineman.
Back in the day, I went to a number of practices when Tubbs was coach. His post players always spend the entire practice working on getting position to catch and shoot the ball around the rim. He didn't want them to dribble unless they absolutely had to, and he didn't want them to ask for the ball unless they were in a position to shoot in conjunction with the catch. He never wanted the ball in and/or around the paint for more than a moment. Inside positioning was not something you did when the ball went up on the rim, but was a continual process every minute of the game. Tisdale was a great post scorer, David Johnson was a great post scorer (even though only -67, William Davis was a good inside scorer (maybe 6'6), Webster, Grant, King and I could go on. There is a real art to inside offensive play and it can be taught. Of course, not everyone will buy in even if taught. I think Luke is getting better on defending in the post. Never going to be a rim protector, but you don't have to be to be a good defender. Getting better on rebounding as well, but he has a ways to go. He doesn't start positioning nearly early enough.
