It's called "small sample size". Both have shown the ability to pass, defend and make open shots in the summer league...less than 10 games. Neither have shown the ability to do so consistently at a high level against high-level compe ion. That's why it's ridiculous to be so assured that one is better than the other. It wasn't so much the position you took as the implication that you were so much smarter than everyone else. The fact is, you're not. And it's not as simple as you make it seem.
The irony is that I also think Simmons has the better shot at being a pro than Anderson because of his speed and athleticism. I agree he has flashed all the tools. But, you also can't deny how much younger Anderson is than Simmons, which gives him the time and opportunity to improve. And Anderson, despite being slower, does have superior size and length for the position. I give both a decent shot at becoming solid pros tbqh.
