An official may assess a technical foul, without prior warning, at any time. A technical foul(s) may be assessed to any player on the court or anyone seated on the bench for conduct which, in the opinion of an official, is detrimental to the game. The technical foul must be charged to an individual. A technical foul cannot be assessed for physical contact when the ball is alive.
So as the ball was live when Draymond’s shove happened (https://imgur.com/a/sbkQB1K), why did they assess the T for it retroactively? Flagrant or common foul if they did not think the contact was enough for flagrant imo.
Truly a Ben Taylor special.
