Amare Stoudamire was a beast the first season after the signing. When LeBron chose Miami, the Knicks pivoted to Amare, knowing that he was injury prone. The Knicks were great that 2009-2010 season, but traded the core of their team mid-season for Carmelo which turned out to be a bad trade. They traded Felton, Wilson, Chandler, Gallinari. That team had chemistry and was very competitive.
Everything went sideways once Carmelo arrived.
