I view internalizing a la Sampras more as a personality type than a gender thing, I know a lot of women like that too.
He was great to watch, but Fed did everything he did, just better...and with a smile on his face the vast majority of the time.
If not for Fed I would not be watching tennis much. I would have just been like all my HS friends who stopped watching basketball when Jordan retired. I did stop for years after Sampras retired, but once Fed started to pile them up in 2004 I had to start watching again.
I'm a bit weird I suppose, the opposite of your point--I like people who remind me of myself. If I wanted to be a different sort of person, I would. But I don't see the value in being a talented jerk, and it's great when someone comes along who is great and relatable. LeBron is like this as well. Even Djok is a bit more accessible than tennis stars of the past. I'm not the guy to glorify Borg's icy calm, cause obviously he was a freakin' weirdo who couldn't bear adversity when it finally came.
