I'd do Lee for Noah, because why not, but as far as Noah's fallen in the last season-plus, I wouldn't expect him to be an upgrade. He's still very good on the boards, but he's become a complete liability on offense, shooting under 41% from 2, and 3/4 of those shots have come at the rim. He also used to be a reliable free throw shooter (in the 70's), but now he's under 50%. He's always been prone to turnovers, but his turnover rate is now 25%. I certainly wouldn't throw a first into the deal.
It's easy to blame Hoiberg and think Brad could fix him, but the decline started last year, and this year has taken an equal step down. It's unfortunate, because he's only 30, and Noah was an entertaining, if infuriating, player to watch.
