What did they do well last season and what did they need to work on this offseason to make a positive jump this season? (notice the word "positive" Dan my Man).

Fears:
His explosiveness and ability to get to the rim is elite, especially when he pushes the pace. He's not Westbrook athleticism elite as in flying through the air, but not many guys are, but his speed, quickness and ability to finish at that speed is elite, and he needs to use it more.
I would like to see a more concerted effort from him to grab defensive rebounds and take off starting the fast break.
Only Flagg averaged more drives to the rim than Fears last year among rookies, and Fears was up there with most average guards in drives per game. The downside was he was only scoring 52% of the time on his 10 drives per game. The better guys are scoring over 60% of the time. Maxey was at 74%, and even his rookie year he was at 72%. Hoping he takes a leap here. I think Maxey is a really good comparison for Fears b/c they are very similar in size and athletic ability.

I think the biggest leap he can take is knocking down 3's. To me, he can be what Tyrese Maxey is. Maxey struggled a bit in his first year but started picking it up in the second half of the year, and he jumped from taking under two 3's a game at 30% in his rookie season to taking 4 a game in year 2 at 42%. Fears shot 33% on just under 4 a game this year. First step is knocking down C&S 3's at a higher rate. He was 33% from both C&S and pull ups. I don't mind the 33% on pull ups, but the C&S needs to be closer to 40%, especially with his ability to cause havoc off the dribble in the paint if he's run off the line. But if you can't knock down C&S 3's at a higher rate, no one is going to run you off the line.

I think one of Fears best abilities is his fitness, and that's an ability that can be underrated. But if you don't use this ability, then what's the point of having it. Fears is never going to be the best halfcourt defender b/c of his size. He's going to get picked on when the game matters. I think one of the best things he can do is pick up guys full court and make them work to get the ball up the court and start their offense later in the shot clock. ORTG goes down significantly the later in the shot clock teams start their offense. I think that's a big way he can make an impact defensively.

Queen:
First thing i hope he worked on this offseason was his lateral quickness. I think he has the ability to be quicker, and this would go a long way as a defensive player on the perimeter.

I want to see more of a David West type role for him offensively where he operates from the elbows. He can knock down that shot and his ability to get to the rim and finish was really good last year. Only 5.8 drives per game, but he scored 76% of the time, which was the best among qualified rookies. Zion causes a bit of an issue in helping create space, but hopefully they can figure something out with him off the ball and how to counter against his man helping. I would think having Queen on the elbow with Trey in that same corner and Zion in the opposite short corner is an ideal setup. Hopefully our new coach has a plan for DQ and Zion when they are on the court together.
DQ only had 1.4 elbow touches per game, but scored on 68% of them, which is where guys like AD and KAT are around, and is really good.
He needs more elbow touches.
I think that is more important than him knocking down 3's, but he still needs to be able to extend his range and knock down top of the key 3's like you see from Jokic/KAT/Embiid/AD There's no reason for him to be anywhere else on the court but within the lane up to the top of the key. I do'nt want to see him on the wing or corner. He should be hovering around the elbows and top of the key for the majority of the offensive possessions.

I do think people underestimate his defense. I think with the right guys around him, he can be better than average as a big defender, both at the rim and on the perimeter.
His DFG% from less than 5' was 65%. Teams did attack him though. Only 15 guys in the league had more attempts per game on them than DQ, and all of those guys that had those high attempts were around that 65% (AD, Embiid, Jokic, Claxton, Gobert, Bam, Mobley none of which were under 60%) Overall he was at 48%, which really is a pretty good number. Not elite, but better than average. DQ was also in the top 1/3 in the league overall as a defender in isolation and on post ups. Pick and rolls were his downfall as he was around the 44 percentile (bottom half). He was actually pretty good defending the 3 as well, holding guys to 32% shooting from 3.
I think the ability is there. The stats back up that he can be a good defender. The first game of the season against Wemby i thought he held his own against him. Just a bit more lateral quickness and adjustments to the speed of the game and i think he'll be just fine defensively, as long as we are game planning correctly and have the right guys around him.. The individual stats show he's a better defender the Missi.
A lineup with Fears/Murray/Trey/DQ and then either Herb or Bey should be a good defensive lineup. If we are making an effort to pick up full court and slow teams down and make them operate later in the shot clock, then we can be a really good defensive team. Good defense also starts with a good offense. Bad 3's and turnovers lead to easy transition buckets.

DQ's best 5 man lineups had Trey/Herb/Bey in them, and either Fears or Jose.
They guys he did the best with this past year were Herb and Karlo, and Karlo's defensive stats are a lot more impressive than you'd think, much better than Missi. Karlo needs more minutes this year.
Fears best lineups had Zion in them.

It will be interesting to see how Murray integrates with Fears and Queen. Murray was a big positive the limited time he played this year, but his worst lineups by far were with Fears and Queen. They were actually the only 2 guys he had a negative NRTG with on the team, by a very wide margin. You'd think Fears and Murray would have worked really well together. Obviously it wasn't a lot of time together so hoping this was just end of season junk that didn't matter much.

I think the biggest job our new coach has in front of him is how to make it work with Fears/DQ and Zion/Murray. Trey, Herb and Bey work well with any lineup, so how we integrate those 4 will be interesting to see. Since we did nothing this offseason, I hope the plan is to see how it goes with everyone healthy and make decisions at the trade deadline if necessary moving out the piece or pieces that don't work with the core group of the future.
