Been thinking about the Capt's post, and I feel the need to explain how I arrive at the conclusions I have. First, yes I usually qualify what I say. I do my best to not post in absolutes. In other words, I do my best to not say this player will never be a star, or the opposite of that. And the reason is, I'm not God! I don't have a crystal ball, and god knows, I've been wrong about as many times as I've been right over the years. So everything I post is opinion, other than the stats or whatever information I accumulate to back up my opinion. I also have info from some NBA scouts that I respect and along with that, I watch an insufferable amount of games on a daily basis. I watched five games yesterday, and still have many recorded that I have to get to.
Watching a lot of games doesn't make me or anyone else an expert. If you don't have other information go along with watching the games, your handicapped out of the box. It's like looking at nothing but stats and thinking you know everything about a player. For instance, yesterday Bagley scored 32 points. OK, that's great, but how many did he score on dunks? How many were 15 to 18 foot jumpshots? Now you can get those stats broken down, but in general, you know more if you actually watched the game. Young is tearing up college ball right now, but would he be doing that if he played on the Florida St. team where the coach constantly rotates players in and out of the game ever 3 or 4 minutes? I don't think so! So then how would you know how talented he is. Would he be the next Kyle Kuzma, whose talent was hidden by the system he played in? Point is, the system a player plays in contributes heavily to what you might see on the court. You need to know the systems to make an educated opinion.
My theory is that if you watch enough games of a player, you'll get enough glimpses of his talent to make that educated opinion, with emphasis on the word opinion. Make no mistake, I think my opinions are the correct one's just like everyone else. And I continue to believe that until I'm proven wrong. But, I will admit when I'm wrong. That said, being wrong comes in degree's. By that I mean, you can predict a player to become a superstar, and the best he becomes is a solid rotational player. Been there, done that! So in the strict sense of the word, I was wrong, but, the player wasn't a bust. He was still a good, just not a great player! The other side of the coin is when you predict that a player will be a solid rotational player, and then they become an all star. Klay Thompson springs to mind. I thought he would be a good player in the NBA, but never imagined in my wildest dreams he would be this good. Ditto Kawhi Leonard!
Anytime your dealing with human beings, your playing with a lot of unknowns. You can measure the talent and the physical attributes of a player, but it's hard to measure his heart, his desire to be great. Especially when he now has 5 or 6 million dollars in the bank and he's only 18 or 19 years old. Was his hard work and desire up to that point to simply make it to the NBA and get that big paycheck, or was it to become the greatest player in the history of the NBA? I want players that would play the game for nothing just to prove their the best. I want players that play because they love playing the game. They love the competition. Those attributes won't always make them superstars, but it will make them the best player they can be with the god given gifts they have. That's all anyone can ask.
My advice to anyone that's trying to form an opinion, is to not read what the draft boards are saying. Other opinions can bias your own, whether you want them to or not. Of course if you don't want to put in the work, I suggest you only read my opinion, because I'm always right!
