I struggle with the constant use of the word "star" or "superstar" on this blog and in NBA journalism. Can someone please define this for me?
With regards to needing one of these players...I think there are maybe 5 guys in the entire league right now that you can take off their current teams, place them on another, and that team becomes an instant contender for a title: Lebron, Curry, Durant, Westbrook, and Chris Paul. To me, this is the only group that the word "star/superstar" applies to.
There are probably 10-15 other guys you can say are almost at that level, and maybe one of them will get there someday. You can't argue that these players really change contender status much because their teams either have multiple other really good players on them (ie Khawi and the Spurs), or their teams aren't that good (Paul George and the Pacers).
Then there are always a few teams in the league that really don't have any of the players in these categories, but those teams are collectively much better. Toronto and Boston this year, Atlanta last year, etc..
I agree that in the Conference or NBA Finals, having a guy like Lebron who can go off for a 45-point night on the road like in Game 6 of the 2012 EC Finals, down 3-2, is invaluable. But honestly there is very little if anything you can do to get a guy like that on your team. You just have to be lucky.
In lieu of waiting for luck, you can build a culture of hard work, effort, defense, togetherness, and competitive spirit. Thats what the 2016 Celtics are about and I love watching them. In that sense, star players are vastly overrated because I enjoy watching this team play basketball about as much as I would enjoy watching any MVP candidate play. And that's what this is all about.
