Which player's game most notably dropped this year? Please don't say Carmelo Anthony because he recorded more ists and rebounds on average than ever and actually took his game to a new level as apposed to those 30-point meaningless games he used to have prior to Billups' arrival. To me it was Allen Iverson. Whilst he's getting old and injured, he was a much better player for Denver last season and just looked to slow down a heap this year. His averages dropped dramatically, and he was even relegated to the bench (despite that being a team/Hamilton thing), but still A.I to the bench? Would never of happened in Denver or Philli. He was also notably poor in the All-Star game. But what do you think?
