I found time to break down 1978 game

First P&R of the game, Gilmore switched into Thompson and showed decent laterall movement but David exploited the switch with excellent pass. I won't call this play positive or negative, but it shows Gilmore's willingness to go outside.
Another P&R and another switch, this time Gilmore's partner showed poor awareness but fortunately the help was there.
Strong boxout - something I criticize Gilmore before. It's important thing to look at plays like that to understand Gilmore's tendencies.
Another good boxout.
Gilmore lost track after Issel's pass and he left him wide open. It's tricky play because Gilmore was supposed to protect the paint, not chase around Issel on perimeter but he could give stronger effort here.
I'll call it netural play - he was in the right position to help against the drive, but he went up for a block too early which gave Thompson small opening. Most players wouldn't exploit it though, Thompson was just terrific finisher.
He might have tried to contest Issel's shot, but this time leaving him wide open was a right choice. Thompson cooked Bulls perimeter defenders.
Gilmore went for Issel fake and didn't recover well. The foul was before the shot, Issel didn't get the basket.
Unlike most big centers from that era, Gilmore was willing to go outside and contest shots and passes. This is not significant play, but it shows Gilmore's tendency.
Gilmore's size intimidated Issel inside, forced him for traveling violation.
Gilmore should have read this breakdown earlier and help under the basket. Instead he did nothing and Nuggets scored on questionable call.
Much better defense on Issel than before. He stayed low, didn't go for the fake and kept Dan in front of himself. Issel scored contested midrange shot but it was good defensive possession from Artis.
I'm not sure how to judge possessions like this one. On one hand, Gilmore should have stayed closer to Issel and tried to contest his shot. On the other hand, he should have stayed inside (like he did) and his teammate should have switched on Issel (which he didn't do). Let me know what you think.
Thompson got the ball inside after terrible defense from Bulls but he didn't even think for a moment to challenge Gilmore. This is typical when you watch 1970s Gilmore - players rarely challenged him inside because he was so big and could get up very fast.
Issel challenged Gilmore this time, but Artis showed nice quickness and rejected his attempt. Refs called it a goaltending, but it was a bad call, which can be seen in slow motion reply.
Another switch on P&R and another solid perimeter defense. Gilmore didn't look much slower than in his ABA years in that game.
Thompson beat his man again and Gilmore had to help, David kicked out to Issel but this time Gilmore made a solid contest (even though Issel made the shot). I praised Gilmore for positive play here because he didn't always tried to recover in such situations.
Issel tried to beat Gilmore off the dribble again, but Gilmore stayed close to him and forced him to turn the ball over.
This is vintage ABA Gilmore with high apex block. Outstanding defensive play.
Excellent P&R defense and good boxout lead to defensive rebound.
Not a huge breakdown, but Gilmore was too focused on Issel and didn't see the threat behind him. That's a bad habit I've seen from older Gilmore, but he didn't make many errors like that in these two games I broke down so far.
Weak effort, Gilmore was inside but he didn't even think about helping on a drive this time.
Bad boxout by Gilmore
Good post defense, steal from behind without overcommiting.
Good help defense, Thompson made another tough shot. There is one small nitpick - Gilmore usually used his left hand to block shots - he could have blocked that one with right hand.
This might be a bit too harsh, but smarter defenders would realize the breakdown earlier and prevent from possible dunk here.
It's the first Thompson P&R that Gilmore didn't switch and he did nothing basically. I don't know why, maybe he was tired at the end of the game?
Good post defense, Issel missed contested turnaround badly.
Gilmore didn't box out Issel, but in fairness, his teammate decided to do that for him and he lost the battle inside. I'd call it a neutral play.
Conclusion:
The goods:- Gilmore was willing to defend players outside the paint and he showed very nice mobility in P&R situations and against Issel,
- he was still intimidating inside, players avoided him and he could still get up very high,
- Gilmore gave Issel a lot of problems inside due to his length and he usually didn't go for his pump fakes,
- he didn't foul much, which is a plus,
- he boxed out better in that game than in 1976.
The bads:- again, awareness could be his problem compared to other elite defenders, sometimes he was too slow in rotations or missed breakdowns,
- again, he was fairly quick for his size but he was a giant so you could catch him in awkward position.
- possible problems with motor, he played 37 mpg in that game so it's not like Bulls relied too much on him and he seemed to be tired at the end of the game (despite having a solid rest in the 4th quarter),
- he didn't contest as many shots inside as he did in the ABA, but to be fair he defended Issel for almost whole game who tried everything to keep Gilmore out of the paint,
- he was at times too passive when he should have helped his teammates more.
I think a lot of differences between Bulls game and Kentucky game is not about Gilmore though. Bulls perimeter players were horrible defensively in that game. They went for fakes, they were easy to blow by, they didn't box out at all and they didn't try to tunnel players into Gilmore. Artis was put into many tough situations and Denver scored a lot of easy points that were not related to his defense. Outside of old van Lier, no guard in this team even seemed to be average on defense, let alone good.
I will watch 1978 game against Blazers next to get a bigger sample, but so far I don't see Bulls problems on defense as a knock on Artis. His motor got worse and he had some lazy moments, but throughout the game he still did most things well and he didn't make a lot of errors. I'm sure that with decent perimeter defenders he'd be capable of anchoring very strong defense even in 1978, but instead he played with bunch of clueless guards.
