I've seen Adams in person numerous times, as well as many many other prospects and recruits over the years. Most go through a freshman year adjustment to the college game so it's easy to predict that. El-Amin had one game driving the lane repeatedly against Florida State and ate the basketball every time, but I think he and Shabazz had quality freshman years and still grew from an excellent start. In Adam's case I'll bite and you can shoot me later in the year. I think he is going to be a star from day 1.
I don't measure this by thinking he will put the team on his back like Kemba and Shabazz. I'm also not saying that that he won't get better and better over time. I'm using the Daniel Hamilton measure. You will always want him in the game. You hate him coming off the floor, you anticipate he's going to make something happen every time he touches the ball. That is in spite of a couple of high turnover games and missing clutch free throws vs Temple. Because of his obvious skills and peak performances, there is a consensus he is a star or a star in the making despite hiccups. I will be shocked if that is not the consensus feeling re Adams.
To say this isn't true because he wasn't a top 10 player means you didn't see the guards ahead of him play. There is no way they were measurably better players than Adams. You wouldn't swap for them. As examples, Trier was excellent but a push. Briscoe shot 1 for 12, turned the ball over, hogged the ball, and generally gave an Isiah Whitehead performance. Other times he had flashes and his shot falls, but is always a loose cannon. We got as good a freshman guard as there is bar none.
