But that playoff rivalry has eroded over the last decade and a half as both teams failed to do much of anything in the postseason, which is a big reason why the reaction to Bills receiver David Nelson’s touchdown celebration on Sunday in Dallas has been more jealous than angry.

Nelson, a 25-year-old Dallas native, just so happens to be dating Cowboys cheerleader Kelsi Reich. And after scoring Buffalo’s lone touchdown in an otherwise miserable 44-7 loss, he raced over to Reich on the sideline, hugged her and handed her the ball.

Awwww, how cute!

Last week Nelson told reporters of his intention to do something “fun” involving Reich if he found himself in the end zone, but said he would not be pulling any Ian Johnson-type shenanigans. Good call there. Proposing after you’ve pulled off one of the biggest BCS upsets in history is one thing. Doing it in the middle of a regular season blowout loss is another.

“It if would have been a better situation, I would have done a little more,” Nelson said after the game. “Being down 14, I’m not going to celebrate too much.”

Sunday’s scoreboard aside, it’s been a pretty good first half of the season for the undrafted second-year receiver from Florida.

Through nine games he’s already surpassed his 2010 season totals in receptions (39), yardage (433) and touchdowns (4). And the Bills (5-4) are in the thick of the AFC East and wild-card hunt.

Oh yeah... and he’s dating a Cowboys cheerleader.

Life is good.
