In the league's NBA Officiating Last Two Minute Report, it was determined by the league that there were a few missed calls in the final minutes.
The one most will remember was a late-game jump ball between Mason Plumlee Karl-Anthony Towns, in which the replay clearly shows both players jostling for position. The league offered this analysis:
[Observable in enhanced video] Both Plumlee (POR) and Towns (MIN) grab one another during the jump ball. A double foul should be called.
The report also says that Al-Farouq Aminu should have been called for a foul on Kevin Garnett at 1:55 and C.J. McCollum should have been called for a travel at 1:12.
Arguably the most controversial no-call was at the end of the game when Allen Crabbe blocked the shot of Kevin Martin to seal the win. The NBA also comments on that play, this time in support of the Blazers:
[Observable in enhanced video] After multiple reviews from various angles, it is unclear whether Crabbe (POR) first makes contact with the ball (or hand as part of the ball)
and then Martin's (MIN) arm or his arm first.
On the Minnesota side, the late-game tip by Andrew Wiggins was also a hot topic. Though considered by replay to be inconclusive when it came to the ability to overturn the on-court call of a goaltend, the NBA's Video Rulebook may offer some different insight on that type play.
