why do we expect people to be gracious when someone is about to break their records?

why do we expect people to be gracious when someone is about to break their records?
i mean honestly ... people are competitive ... they play to be great and if they set records that means their number one
when someone breaks it they can no longer compete and it's like dang it
of course over time variables change, game numbers, styles, sorry teams
i'm just sitting here and they keep talking about the guy from ucf about to break barry sanders record
and why should barry be nice about it
