Surprised that people don't rate Kemba - he was still fairly good last season and I expect him to make the contract New York signed him on the best bargain deal in the NBA.
The guy is a defensive turnstile with a banged up knee and on the wrong side of 30. I was ok with the Celtics trading him for a bag of chips.

Defensive turnstile who posted a positive value in most adjusted plus-minus metrics this year and still pumped out fringe All-Star value on offence (especially after he got his sea legs back) - here are Kemba's numbers after his dismal first 10 games last season:
Box stats - 20.6/+1.6% PPG to rTS, 23.6%/11.1% assist rate to TO rate
Adjusted plus-minus - +2.6 OEPM (94th percentile), +0.1 DEPM (63rd percentile), +2.7 EPM (85th percentile), +3.5 ORAPTOR (27th in the league), +0.4 DRAPTOR (tied for 16th among point guards)
Before you start nitpicking the list of names in those metrics to dismiss them as stuff made up by nerds that are infinitely worse than the basic box score in measuring a player's value, there's definitely some noise to single-year APM (it only estimates a player's
situational value in that given year, which can either go wrong because of wonky lineup data or poor situation/fit for the player in question), but the fact that Kemba produced such numbers in a situation that everyone and their grandmother on this forum screamed was far from ideal speaks volumes to his quality. And before the narratives of statistics lying about how good a player is start flooding in, the numbers jive with the eye test. Kemba was still a dangerous PnR ballhandler who strains defences with his ability to pull up for three on high volume and good efficiency (he shot 37.4% on 8.5 attempts after his first 10 games), drive to the basket for layups or floaters, counter defences running him off the line and sitting in the paint with a quality in-between game and find open teammates if defences collapse on him. On defence, he's active both as a man and team defender, makes good rotations (his ability to take charges is elite) and does a decent job at staying in front of his man as a point-of-attack defender. I completely understand scepticism about him if someone drafted him to start for their team, but how many backup PGs in this format are better than Kemba Walker as a basketball player? Good offence and decent defence, what more do you want for someone to run your offence for roughly 10-15 MPG?
