Watching that final I see Vilas was using his slice all the time, like in the US Open final against Connors; but that was not working. When he attacked and did some risky shots, he caused troubles to Borg, for example when he breaked his serve in the third set; but after that he started to use the slice again, not attacking. I wonder why he didn't try to play more aggressive! It looked like he didn't believe he could win.
