I watched the game on TV, a few thoughts:
There's no doubt Lewis has a TON of upside - he's got the size, athleticism, ball handling, and shot to be a big time SG. But I don't think he's a day 1 starter - he's pretty skinny, his D will need a lot of work (not a surprise for a frosh), and he'll have to adjust to bigger players inside.
I have a ton of respect for those who scout full time. Obviously so much more goes into it than seeing one game. Lewis plays for a high school team that lost 3 players before the season started (injuries/transfers etc) so his team is still trying to figure it out.
If I had just seen the first half, Lewis barked at his teammates, was somewhat lazy at both ends, got lost on D, forced shots, and his team was down 18.
In the second half, he drained 3 3's, dunked, took the ball to the basket for reverse layups, made free throws, and made a few 15 ft turnaround/fade aways. He dominated that last 5 minutes of the game.
If Prohm is going to play 3 and 4 guard line ups, Lewis is the perfect player for us. Huge upside, but let's tap the breaks. He'll need a little time.
