Fifteen years ago the most dominant player in the league was 7'2'' 300+ pounds. He broke the game by being bigger and stronger than everybody else.
In today's league, the most dominant player in the league, when everybody is healthy, is a 6'3'' guard with an elite handle and finishing ability, good passing and stealing instincts, and the deadliest jumper -- especially from beyond 25 feet -- the league has ever seen. He breaks the game with his ability to punish every little mistake an opposing defense makes, and he not only creates opportunities for himself, but also for others.
I'm pretty much OK with the league as it is.
I do think the power forward position is getting phased out a little bit, and that's somewhat concerning. It does seem like it's better to have an adequate but unremarkable combo forward who can hit open three pointers than it is to have an elite physical specimen with a great back to the basket game and limited range. In other words, you might be better off with Marvin Williams at the 4 than Derrick Favors. In the Finals, the Cavs were far better with Richard Jefferson on the floor than they were with Kevin Love.
Maybe that's a problem. On the other hand, maybe the Derrick Favors of the world will just need to develop a passable three point set shot. Maybe the Kevin Loves of the world will be relegated to backup roles because they can't reliably defend anybody who can actually move their feet.
Maybe that's a good thing. I dunno. Either way, I'm not in a panic about it.
