the L2M report was released and the nba admitted it missed two calls that would have favored the C’s:
1) a missed lane violation by caleb martin on a free throw JB missed with 1:01 remaining in the fourth quarter.
2) a foul on JT by gabe vincent on a drive to the basket with 33.5 seconds remaining.
however, they doubled down on the butler double dribble by claiming it was a legal play.
it also confirmed joe’s challenge gave the NBA the ability to look at the entire play, in which Horford's foul occurred with three seconds to go, adding an additional nine-tenths of a second to the clock.
