- Sampras usually only looked "mentally strong" when the conditions suited him and it was likely that he SHOULD prevail anyway.
- Similar thing with Federer: His greatest comebacks in matches usually came against opponents he should never have fallen behind 0-2 against.
- If Sampras wouldn't be introverted, he could have been a McEnroe type of jerk on the court. Because he actually questioned a lot of calls he was CLEARLY wrong about. Only that his typical reaction wasn't swearing or discussing, but standing like a statue for seconds, staring at the line or the judge and not walking to the other side. I remember how often I thought "Not this again, move over now".
- Federer could REALLY be a bad loser at times.
- Federer kind of "wasted" the 7 years between AO 2010 and AO 2017, and that costed him the GOAT title. And yes, I know that most players could only dream of having those 7 years, but Federer isn't "most players".
