I think I can explain this
Zeller is 2 inches taller and 2 years younger than Jordan Hill. He's also about 18 pounds heavier.
Jordan went for 12 pts and 8 rebs last year on a horrid Lakers team that was trying to tank. Those were career highs for him.
He didn't start all his games. He played 70 games while T Zeller played all 82 plus playoffs. Hill has never played more than 72 games.
Jordan's career fg% is .495 and he hit his career high in ft% last year at .738. He has never averaged a block a game. The highest he ever hit was .9 twice. Last year he went for .7 despite playing his career high of minutes. He has also averaged over .5 steals a game once.
Hill also has at least a concerning injury history.
Ty Zeller....His career fg% is .505 and his career ft% is .776 in three seasons. He has played over 70 games all three of his years, including last year when he started 59 regular season games for the 7 seed in the East.
For whatever reason he didn't play tons of minutes last year. He played 21mpg. Let's for math say he played 20 and then increase his stats by a third hypothetically. He averaged 10, and let's say 6 (actually 5.7). If you increase his minutes from 20 to 30 then proportionally....at 30 minutes a game, he's averaging 15 and 10, and Jordan hill can't say anything like that. He'd also have about 2 assists and a block a game.
Zeller isn't great but he's a better player than Jordan Hill.
