Two things, Bobble. Let me edumucate you. First, as far as meeting celebrities, the key is that we generally meet them once. I love that Terrell Owens was cool, and all power to him. But Jeter - maybe he had a hemmhoroid that day, or he just found out his mom was having an affair with his best friend; I don't know. Or maybe he IS an asshole. I have no idea. But meeting someone once - it's maybe not a good idea to judge that, although I agree with your implicit assumption that celebrities KNOW this and really ought to be on their best behavior with the public. But they're human. And like I said, Derek Jeter may well be an asshole. Your perception might be right.
But on to my bigger point: it is a little know FACT that Greg Jennings's sister is, in fact, Aaron Rodgers. Don't aks me how I know that; just know it's true. So yes, Greg Jennings's sister does understand offensive schemes, not better than Aaron Rodgers, but just as well.

I'll agree its not fair to judge a person based on one meeting in a casino no less, but I can give 2 examples that speak to character. TO telling his posse to stop cursing in front of women. Thats not nothing in my book (plus he was super nice to EVERYONE). Jeter acted like the high school jock you wanted to punch in the face (unless you are Nutz, in which case you WERE that guy...kidding nutz). He belittled his "friends", had a general arrogance, and stiffed the waitress that brought him a drink. I asked her later if anyone in his crew took care of her and she said no. Ball busting among friends is awesome. With the Jeter "crew" it was him being a dick and his posse telling him he was great. Its a snapshot, but its an ugly snapshot.
I don't hold Grudges. It's counterproductive.
