Let's go over Jabari Parker's tenure with the Bucks:
December 2014-tears ACL
November 2015-returns from ACL tear
February 2017-tears ACL again
February 2018-returns from ACL tear
In the 4 seasons in which Jabari was a Milwaukee Buck, out of a possible 328 regular season games, Jabari played 183 of them. That's 55% of games played. He never got full run as a Buck and the longest tenure he got was just over one full season, however that doesn't include the month or so it took for him to get back into game shape and get regular run.
Rift with Giannis/team-in 2017, a players-only meeting took place where Jabari spoke very publicly about what happened stating, "there was a meeting about the players and it didn't go my way. I was getting thrashed, but hey, as long as they see my perspective." He was subsequently benched for the following game by Kidd.
Rift with Kidd-it has been widely reported that Kidd and Jabari didn't like each other, even to go so far as that they never spoke. This was a huge point of contention and I'm sure was a major reason why Jabari didn't get along with his teammates as well. It's hard to fault Jabari for that, Kidd was an awful coach who played favorites. But keeping Kidd around certainly didn't keep any hope of keeping Jabari long term, even after Kidd was gone.
Body language-Parker's body language was always bad. Watching a lot of games in person and almost every game on TV, he spoke very little to his teammates, interacted very little with them on the floor. He has always been an introvert, but that clearly affected his chemistry with the rest of the team.
Defense-Jabari was never going to be known for his defense, but in 4 years, it never improved and much of it had to do with his effort. Jabari showed the ability to defend guys 1 on 1 and do it well. But when it came to talking on the court and maintaining his spots on defense, he showed little effort. It was reminiscent of him on offense. When the ball wasn't in his hands, he wasn't an active participant in the game. The same goes for his defense. If the man in front of him didn't have the ball, he cared very little. And that doesn't even begin to touch on his effort level. He routinely jogged back on defense, failed to ever get back in transition and that affected his chemistry with Giannis.
Contract signing with the Bulls-
The Bulls signed Jabari to a 2/40 deal with a team option for the second year. Lets get a few things straight. For one, you CANNOT sign and trade a player to a contract under 3 years. The Bulls clearly never had any intention of giving him a fully guaranteed 2 year deal, let alone 3 years. That's reason #1 a sign and trade didn't happen. Reason #2 is that the Bulls had no need to sign and trade him. They cleared a bunch of cap room by releasing Paul Zipser, Sean Kilpatrick, trading Jerian Grant, and renounced free agency rights to Noah Vonleh and David Nwaba. They did all that to get to an area where they could offer Jabari $20M per year. The Bucks, after signing Ilyasova and Lopez, could not fiscally match that contract. They were hard-capped. It could've been more plausible if they worked out the Jabari situation first, THEN signed Lopez and Ilyasova, however, if they took back anything of monetary value (they would've had to) they would've been over the luxury tax line. That, in turn, makes them a luxury tax team. They offered Ilyasova a 3/21 contract using their mid-level exception. There are two MLE's, the tax-player MLE and the non-tax payer MLE. The tax-player MLE is around $5.2M per year. The non-tax player MLE is $8.3M per year. If the Bucks entered luxury tax scenario with the Jabari situation, they couldn't have offered Ilyasova a 3/21. I guarantee the Bucks didn't willy-nilly throw out a 3/21 to Ilyasova without doing their research first. Ilyasova was going to get paid and fast. And my inkling is that Ilyasova was going to get a comprabale contract to the 3/21. If the Bucks came out on the first night of the draft and told Ilyasova they could only offer 3/15 (being the tax-payer MLE), he probably turns it down and takes a bigger contract that was out there for him.
There has been so much conjecture about Jabari and yes, it sucks getting a #2 overall pick and ultimately losing him for nothing at the end of his rookie contract. But one of the reasons I keep hearing Bucks fans are so upset is the argument, "we're paying Snell, Henson and Delly X-amount of money, and now we're not going to pay Jabari?" YES! You don't compound one problem by creating another. At some point you have to be fiscally responsible. Horst took over this team with those 3 under contract already, so his hands are tied. And if we matched a Jabari contract, we'd just lose him to free agency again next year, because we'd then have Brogdon, Middleton and Jabari as free agents. CHI also won't hold any rights to Jabari next summer if they decline his team option. So in essence, it's a rental for Jabari.
Look, I think Jabari is going to be addition by subtraction. He was shoe-horned into lineups to get him minutes. He didn't start because he didn't fit with the starting lineup. And that starts with the fact that he's a bad fit alongside Giannis. The Bucks were bad because they never had floor spacing. Bringing back Jabari just compounds that problem. Bringing in Ersan and Lopez is going to do wonders for this offense. For example, one of Bud's assistants is running the summer league team. Assistants run the same type of sets the head coach will run. There was a highlight floating around where there was 3 players all stuffed into 1/3-1/2 of the floor. In a matter of 5 seconds, all three of those players occupied the corner-3 spot basically running a circle around that corner. It led to a guard getting a wide open look from that corner 3 spot. That's how you utilize every inch of the floor. Kidd and his cronies were allergic to not only 3 point shots, but to the corner 3, the most high percentage point-per-possession shot in the NBA. Look back at the offense the last few years. How many 3 pointers do you remember coming wide open in the system, not just based off of Giannis gravity driving? How many 3's do you remember coming at the top of the key or baseline extended? That is the longest part of the 3 point line. That, aside form a long-2, is the worst shot, point-per-possession in the NBA. Kidd and company force-fed those shots constantly. Bud is going to open this sytem immensely.
