He had 2 things that Fultz didn't. He had good teammates around him and he had a coach that put the players in a position to succeed.
Sure but those good teammates were 15-17 the year before. Leaf was great but it's the same Leaf everyone said was NOT a one and done before he arrived at UCLA, the same Leaf that Sean Miller was clearly mocking when he was talking up Markkanen and bashing Leaf before either had ever played in college. Part of why Leaf was better than expected is he played with Lonzo and got the ball where he could do damage.
Same with Anigbogu, before the season many people had never heard of him. He played 13 MPG but he's big and athletic and those lob dunks from Lonzo caught the attention of pro scouts.
I don't think Alford deserved the banners and nonsense like that but I don't think he's a great coach either, he was just smart enough to realize how good Lonzo was, and let him do his thing. That's coaching too but it's Lonzo that made it work.
UCLA had more talent this year, 16 wins more talent than last year I don't think so, they just played better because of Lonzo Ball IMO.
Great players should be able to make an impact on wins and losses. UCLA actually beat UW worse with Fultz than without him, and that game was at UW.
