This question is too broad, since basketball is played over such a broad area in many different ways. But since the question stands as is, I’ll vote axcordingly.
I gave it a 3.
I loathe the NBA and would five it a negative score if I could. The fact that the NBA is starting to dip in popularity right now makes me smile, because I hate the NBA product. I’m amazed that it is still as popular as it is, but when Stern resigned, it was a signal to me that he sees the writing on the wall. The next decade will be painful for the NBA, and at the best, there will be flat growth. Stern got out while the gettin’ was good. He was a rat that bailed on a sinking ship.
However…
College basketball is still a great game to watch, and I can stop and watch just about any college game on TV, and iI enjoy it enough to not immediately look for the remote. I enjoy March Madness, and I don’t really care who wins the tourney. Of course, if my team would win, that would be great, but since they never do, it doesn’t detract from my enjoyment of the tournament.
It is also a great game to play in the summer or when growing up, so the game has a lot of appeal to me from a personal level.
The NBA, though, where the highest level of basketball talent plays on a daily basis, is a lousy league that has permitted the game to get too sloppy for my tastes. There is rarely a traveling call any longer, and 3 seconds is more like 6 or 7 seconds, if it is called at all. Many of the rules learned when I grew up playing in high school have been erased in the NBA to make the game “better”. However, I personally disagree that the NBA game is the best product out there. The NCAA game, to me anyway, is where the game reaches its best level, even if the talent level is much less in college.
I like certain players in the NBA, like LeBron James and Kevin Durant. However, I don’t care about the Heat or Thunder at all. I can appreciate the skill of some of these guys, but the game is a bastardization of what it was and I simply don’t like what it has turned into.
ETA - forgot to mention the WNBA, which is an abomination. I can’t watch it at all, and yes, I know these women are great players. However, the game they play is too slow, too error-filled, and this game wouldn’t have survived this long if Stern didn’t connect the TV rights of the NBA games to the WNBA. This is a horrid product.
