UPDATE: J.R. Smith said he did not post "Cavs in 7" after Cleveland's Game 3 loss.

"I got out of the shower and my phone was buzzing. I did not tweet that," Smith told Cleveland.com after his postgame locker-room interview session.

"I'm smarter than that."

ORIGINAL STORY:

The Cavaliers were on the cusp of making the NBA Finals a series, only to have it taken away from them by Kevin Durant and the Warriors in the final minute of Game 3.

The Warriors won the game, 118-113, to take a commanding 3-0 series lead and all but assure themselves a second NBA title in three years. But Cavs guard J.R. Smith doesn't think it's a foregone conclusion.

Just minutes after their heartbreaking loss, Smith tweeted out "Cavs in 7" for the world to see.

Smith deleted the tweet about an hour after posting it, but it's not clear why. It's not like he's saying anything the Cavs aren't saying in the locker room. There's surely a rallying cry of, "We came back from 3-1 last year, we can come back from 3-0 this year!"

Sure, it's unlikely, but Smith shouldn't be ashamed from sending out tweets saying that he still believes in his team.

After a quiet first two games, Smith had a breakout performance in Game 3, hitting five 3-pointers and scoring 16 points in the loss. He'll try to have a repeat performances in what he hopes is the Cavs' first win of the series in Friday's Game 4.
