PK is short for Pick, or Pick ‘em. When you see that on a NFL betting line is means the game is considered to be even. For example, if the New York Giants are playing the New York Jets and the line is PK that means it’s considered an even game. There is no point spread. So whatever team you bet, the Giants or the Jets, just has to win the game for you to win your bet. “Pick’’ games don’t have very often in the NFL. In the entire 2018 regular season (256 games) there were only six games where the line closed as a Pick. There were no “Pick’’ games in the NFL playoffs in 2018.
