I remember we had this WR named Kelley Washington in the mid 2000s, and he was nothing special. He turned up on the Ravens in 2009 the year they crushed us in the playoffs. I still remember him looking into the camera on the field after the game and yelling "It's over! The dynasty is over!"
At the time I was pretty mad about the playoff loss and for some reason him yelling that really stuck with me (as you can tell).
Since then the Patriots dominated the league for another decade and won three more Super Bowls. So sometimes I think about Kelley Washington and how gleeful he was to beat his former team, and how wrong he was with his proclamation, and how much of a nobody he is in general.
Anyway, in conclusion, I'm pretty sure that the OP is Kelley Washington.
