In classical logic there is a fallacy known as "post hoc, ergo propter hoc" (after X, therefore because of X). It is a fallacy.
There is legitmate ground for criticizing Gallinari, particularly in light of the hyped support he seems to be given by management, but to suggest that the Knicks are better without him or that he is responsible for the current string of losses is ridiculous.
Over the last five games -- all losses -- Chandler has averaged 10.6 points at a field goal percentage of .348 and a 3 point percentage of .181. Felton's numbers for the same period are 12 points a game, a .291 field goal percentage and a .285 3 point percentage. Amar'e's percentage for the five games is .423. For the season it is .498, a number below his career percentage. Fields' numbers are reasonably steady but his season field goal percentage is .517 and for the last 5 games it has been .423. But Fields does not take a lot of shots. He has taken only 32 over the last 5 games. Amar'e has taken 111, Felton 79 and Chandler 66.
Over the last 5 games Gallo has taken 43 shots, at a field goal percentage of .465. He has taken 15 three point shots and converted 5 for .33. He has averaged 16.8 points a game.
Our recent problems are primarily the poor offensive play of Felton and Chandler. We were winning in large part becuase of their stellar play. During our losing streak Gallo's play has improved. He is not the current culprit.
