LeBron: No regrets over dunk tweet
Thousands took to Twitter to comment on the slam last Monday, which saw Griffin rise up and on top of Perkins before powerfully throwing down, with many declaring it one of the greatest of all time.
But Perkins seemed to take issue only with James' post.
"Dunk of the Year! @blakegriffin just dunked on Kendrick Perkins so hard!!! Wow! I guess I'm No. 2 now. Move over #6," James wrote, referring to his own spectacular alley-oop dunk from a day earlier over the Bulls' John Lucas III.
"You don't see Kobe (Bryant) tweeting," Perkins told Yahoo! Sports on Tuesday. "You don't see Michael Jordan tweeting.
"If you're an elite player, plays like that don't excite you. At the end of the day, the guys who are playing for the right reasons who are trying to win championships are not worrying about one play.
"They also are not tweeting about themselves talking about going down to No. 2. I just feel (James) is always looking for attention and he wants the world to like him."
Asked about Perkins' comments Wednesday, James said no apology was forthcoming, the South Florida Sun Sentinel reported.
"From day one, that's why I got to Twitter, to connect to my fans. I would never apologize for anything like that when I'm connecting with my fans," James said.
"I can see why he may have felt embarrassed," he added. "(But) I don't think I was the only one that reacted to that unbelievable play by Blake, and that's what it was all about, me acknowledging how great of a play it was.
"If Kendrick Perkins had dunked on somebody else on the other end, I would have done the same thing."
Griffin's dunk drew comparisons with his similar effort over the Knicks' Timofey Mozgov last season, and within minutes "Blake Griffin," "Kendrick Perkins," "#dunkoftheyear" and "Mozgov" were all trending nationally on Twitter.
Even NBA.com's Twitter account got in on the act, tweeting, "WOW!!!!!!!!! Perkins just got Mozgov'd by Blake Griffin."
