The Los Angeles Lakers traded for Roy Hibbert last offseason in an effort to fix their defense. The prevailing thought was that if Hibbert could maintain the effectiveness he showed at using "verticality" to defend the rim in Indiana with Los Angeles, then the Lakers could take steps towards fixing their moribund defense.
Anyone who watched the Lakers last season knows how that worked out. Hibbert’s effectiveness as an impediment at the rim was compromised by a combination of poor wing defense and a poorer scheme that saw him deployed too far away from the rim to make an impact.
