It's both a nominating provocation and an open question as there's no beat writer I read more often. His blog post this afternoon (an off day, I add) about the discrepancy between Larry Drew's words action regarding Jeff Teague is an example for anyone writing about basketball. It has it all: research, quality prose, sharp questions, and expansive quotes for the answers to those questions.
To whomever compiles the best basketball writing of 2010: do not less this pass you by.
