Was the Dallas Mavericks trade for Kristaps Porzingis from the Knicks a failure?
Yes, it was a failure, but only when examining the results. Porzingis was an All-Star in 2018 before tearing his ACL, but he never returned to that level in Dallas. He never played more than 57 games in a season for the Mavericks and was haunted by knee issues and injuries at every turn.
KP never became the second star the Mavs wanted next to Luka Doncic. His health, defensive struggles, and limited offensive skill set all played parts in Porzingis failing to reach that status.
A case can be made that Tim Hardaway Jr. was the most impactful player Dallas acquired from the Knicks in this deal. He played 70-plus games in each of the last two seasons as he blossomed into a lights-out shooter in Dallas. Hardaway Jr. went from being on a difficult to trade contract to re-signing a four-year $74 million deal to remain with the Mavericks.
Trey Burke also remains on the roster and has been a steady third-string point guard for Dallas.
The Kristaps Porzingis trade with the New York Knick was a failure because the Dallas Mavericks gave up two first-round picks and did not land a second star. They acquire three role players that had varying degrees of impact, but that was just not enough.
