I'm skeptical that Leuer can play the 3. I'll follow that up by saying I've never seen him play. He might have a good enough outside game that he can sit outside and put up j's. However, that is only 50% of the game. The rest of the time he has to defend someone. I'm skeptical that he could defend the 3rd guard that many teams employ these days.
Even though bringing in Walker, Brackins & Leuer might seem like overkill- it's not like we have any All Big 12 post players on our current roster. Is Hubalek a Big 12 starter or just a solid reserve. Same goes for Alex Thompson. I realize a lot of Cyclone fans love Ross Marsden, but I doubt he would have played much for a KU, UT, OU, etc last year. Ross is young & post guys take time to develop, but I question if he'll ever be a quality Big 12 starter or backup. I like Ross' offensive potential, but I wasn't impressed with his defense or rebounding last season- at times it looked like he was wearing cement shoes.
I hope that doesn't come off too harsh, because Hubalek, Thompson & Marsden could end up being quality Big 12 starters, but each is an unknown. Last season proved a team can have superior wing players, but without a consistent low post offensive threat & some toughness down low on defense it's tough to compete in the Big 12.
