Before the regular season comes the preseason, a series of games in which players sharpen skills and get into top condition, and coaches evaluate said players. These exhibition games don't count in the the standings.
Before the reseason comes the P. This letter always matters. It's an important P — a VI P.
So, what happened to the pre-reseason P at 4 o'clock?
It occurred beforehand. (See the 1 p.m. listing.) In other words, it was preexistent. At 4 p.m. it was no longer pre- existent.
Like Minnesota Vikings running back Adrian Peterson, it didn't take part in the preseason.
