Someone else originally posted it was a goal tend by rule.
I never agreed or suggested it was, only questioned it..
Then I said it was a reviewable play.
To me it looked like a good block at the time.
I posted the rule and by rule it was a goaltend when Lebron pinned the ball briefly against the backboard. It happened too fast for the refs to catch it, but there are pictures that show it. Definitely reviewable, but it was so fast that I don't think the Warriors caught it...at least I don't remember them complaining.
