IMO, what Weber's tenure at Illinois has shown is if you put a premium on shooting and don't shoot well your offense will struggle. Even the last 6 years, Weber's teams have consistently out-shot their opponents (eFG%), an average of nearly 4% better per season. For Frank's teams the difference was slightly less than 1%. But the difference in TO% and OR% for Frank's teams are both dramatically better than Weber's and that's why Frank's offensive efficiency was much better. Weber's teams have had better defensive efficiencies (89.7 his last 6 years compared to 91.2 for Frank's 5), but it wasn't enough to make up for the offensive issues.
