Heard Michael Rappaport blasting LeBron because at the end of the half AD landed in Kevin Hart's lap and it became an organic, very funny, cool moment but, and this is Rappaport's words not mine, LeBron had to run over and get involved because he is such an attention hog and diva he couldn't allow his team mate to have that moment without him being involved too.
I know nobody will remember this, but back when the Rams were the greatest show on turf (99-00), a relatively unknown receiver named Ricky Proehl had a huge NFC Championship game. During his post-game press conference - probably the only time he was ever involved in one of these - Kurt Warner came out from the locker room (or wherever; he was not involved in this interview) and obnoxiously and uncomfortably yelled "Ricky Proehl" like 3-4 times. Ricky Proehl's big moment became overshadowed by Kurt Warner being a doofus. For years, my good friend and I have referenced this as a prime example of someone being a db.
Even though James is an extremely talented, hard-working, generally good person, he just can't help from trying to be the center of attention. Don't get me wrong - I am no Lebron fan - but this particular quality of his is extremely unbecoming and a huge reason (other than him being so good for so long) that so many people dislike him.
Ha, I've heard the same accusations about Hulk Hogan For the old school wrestling fans, WrestleMania 4 and WrestleMania 6 are some of the earliest examples (believe it also happened with WCW/NWO, but didn't follow that). So in WM4, Hogan wasn't even in the main event, but he got himself involved in the match and was posing in the middle of the ring and celebrating after Macho Man won. Supposed to be Macho Man's big moment, but Hogan found a way to put himself smack dab in the middle of it.
Similar thing in WM6 when Ultimate Warrior beat Hogan. Hogan made sure he was involved in the post match celebration: made a big presentation out of giving Warrior the belt, shaking his hand, raising his hand, etc.
These are supposed to be the biggest moment in these other wrestlers' careers, but Hogan made sure he's there celebrating with them, while nobody else ever celebrated with Hogan the numerous times he won the championship.
Now it's pro wrestling so it's all scripted, and listening to some of the podcasts about the era (like Bruce Prichard's) you constantly hear one of Vince McMahon's big things for a show was "Hogan must pose" to give the fans what they want. For showmanship and story line reasons, I can see the reason for Hogan being there in somebody else's moment. Though, even though it's all scripted, there's also a lot of backstage politicking involved, and some argue Hogan politicked his way into those moments to make sure he was still be front and center when it was supposed to be someone else's turn in the spotlight.
