Partly it's the same thing that's wrong with this website: a severe lack of effort. Maybe the team hasn't bought into coach David Blatt's system. Maybe LeBron James is a prima donna who has undermined his Euro-League legend and NBA rookie head coach. Maybe the defense is lacking a true, rim-protecting big man (a need that was harped endlessly on this site and other prior to the season even beginning). Maybe it's an aging bench, or a crappy system, maybe it's an insistence on having our big men hedge on screens and chase players too far from the hoop.
Maybe it's all of that.
But, and I'm spit balling here, maybe it's the declining play of LeBron James.
