Connors is an asshole and when he played, his nose was coke-full. One of the reasons why he never gave up (and also why he implied in some rehab associations when he retired from the game). But he also was the ultimate showman, that is so true !
Remember this game in Paris (1990 or 1991, not sure) against Chang. He was more than tired, couldn't even run, and he quit the match after having scored the 1st point in 5th set, just to say that he was ahead when he gave up

About best games per decade :
1970's :
I was born in 1975, so I'm too young to remember tennis games I've (maybe) watched in the 70's
.
1980's :
McEnroe - Connors, Wimbledon, F, 1984 : 6-1 6-1 6-2
For sure, not a tight game, but probably the greatest performance to the net I've seen in my all life. Mac was flying this day, making love with balls and lines. Incredible.

Agassi - Sampras, Bercy, QF, 1995 : 7-5 7-6
Only a QF, that's true, and certainly not the most famous game between these 2 legendary rivals. But this match level was totally crazy. I was in stadium (lucky me) and it was like some ping pong game as it was so quick, with 2 guys playing backcourt semi-volleys half of the time ! A very few errors, tons of winners, incredible game !
https://youtu.be/EAKZuG_llsM2000's :
Nalbandian - Federer, Tennis Masters Cup, F, 2005 : 6-7 6-7 6-2 6-1 7-6
Nalby played like god in the last 3 sets (same level than in 2007 when he won back to back Madrid and Bercy, beating each time Nole, Rafa and Roger !). The only guy able to come back from 2 sets 0 vs Fed indoor (Nadal did it same year in Miami if I'm not wrong).
https://www.youtube.com/watch?v=Bm_wClDQoa02010's :
Djokovic - Nadal, Australian Open, F, 2012 : 5-7 6-4 6-2 6-7 7-5
Almost 6 hours of total war, the greatest game ever in my opinion. I was in front of TV for the all game and was so tired at the end, as if I just came to really play tennis as it was such an intense match !

Forget - Sampras, Davis Cup, F, last game, 1991 : 7-6 3-6 6-3 6-4
I was 16, I was in stadium, 8 meters from the court, I gave many punches on Bolletieri Uncle Sam hat who was sat just in front of me, I sang a capella Saga Africa with Noah and all supporters at the end, I cried, I was nuts... What else ??!!!
