Placing the burden of carrying a team on any one player is foolish.
In addition, Mike D'Antoni should know better than to use the concept of "lead dog" to the media as they will only use it to brew dissension. D'Antoni must adjust his strategy and vocabulary to a team that starts three veterans, all who are capable of leading, on offense.
First, scoring points is only one aspect of the game. Anthony, Stoudemire and Billups are ALL capable of significant offensive output on any given night.
Second, Mike D'Antoni SHOULD be concerned with is getting his rookie prodigy, Landry Fields, involved in the offense. Field's now suffers from being ignored more than Danilo Gallinari ever was, and as a result, the Knicks versatility is limited.
Third, but not least, forget about scoring stats. Who is making the key stops (or grabbing a man's rebound) when the game is on the line? Who is the leader for establishing a playing personality on defense?
Defense wins championships in the NBA. You need 5.
