It's simply not true that Lendl never came close to a tantrum. Everything that Moose listed above is a part of the record and can be checked -- and I think Moose was quite correct where he placed Lendl: not as bad as McEnroe but certainly not as quiet as Borg or Edberg.
I will never forget that '89 match in Dallas against McEnroe. After what he thought was bad call, he was so enraged, he rounded on Gerry Armstrong and lifted his voice to a hoarse fury. It was scary, in the sense that I think Moose meant it -- not perhaps for the umpire who knows how to deal with such things, but scary to watch (perhaps to some degree because Lendl did not do it all the time, but also because, yes, it was a bona fide temper tantrum -- and not a mild one -- coming from a great champion).
Lendl got penalized the next point for an obscenity; he denied uttering it and refused to play, for which he was docked the game.
In his previous match against Jakob Hlasek, he'd also been assessed a game penalty.
The actual revisionist history on Lendl may be coming in the future, because so many people go to YouTube for tennis history, and on YouTube the time between points often gets cut out. That 85 AO match, where Moose said Lendl complained as much as he ever saw anyone do, is now on YouTube -- but just the tennis, none of the stuff in between points. In our YouTube culture I think it's probably going to get easier and easier to forget Lendl's behavior and to remember just his tennis.
Here's a link to a 1982 article about Lendl stopping play for ten minutes and eventually giving the finger to the crowd:
