Lost in the hubbub of the Hawks-Warriors showdown Friday night — a game featuring the NBA’s two best teams, record-wise — is the fact Atlanta had to close out the weekend against the Memphis Grizzlies, the team that currently holds the third-best record in the league. An offensive foul from Atlanta’s Al Horford in the closing seconds of the third quarter gave Memphis an extra possession, and the Grizz capitalized on this nifty inbounds play, in which Mike Conley received the initial pass, and promptly lobbed it to Kosta Koufos for the buzzer-beater dunk.
