CLEVELAND — Browns safety Damarious Randall underestimated two things: the power of social media and passion of Cleveland fans.

Randall said Wednesday he never imagined that an innocent Twitter posting about the NBA Finals would blow up into a national story — and maybe something he lives to regret.

A big fan of Golden State star guard Stephen Curry, Randall posted a tweet on Monday night promising that if the Cleveland Cavaliers beat the Warriors in the “2018 NBA finals, I’ll buy everyone who retweet’s this a jersey.”

By Wednesday afternoon, Randall’s tweet had been retweeted 869,000 times.

“Honestly, I didn’t think it was going to get over 100,” Randall said after practice. “I didn’t think people were going to actually view that as a serious tweet from me. But obviously it got the whole world excited about it, and I mean now I’m actually excited about it.”
