1 year ago Good catch! This seems to be a rare case where nflfastR can't recognize a PAT (either 2pt or XP). Since it doesn't know it's PAT, EP is quite high on these PATs. I think the other EP values are affected by this.
pbp <- nflfastR::build_nflfastR_pbp(c("2021_13_LAC_CIN", "2008_10_SF_ARI"))

(game_id == "2008_10_SF_ARI" & dplyr::between(play_id, 4080, 4114)) |
(game_id == "2021_13_LAC_CIN" & dplyr::between(play_id, 1518, 1573))

Examples: 2008_10_SF_ARI play_id's 4080, 4094, 4114 2021_13_LAC_CIN play_id's 1518, 1573, 1538
On the timeout "play" the ep is calculated as if it's a regular play near the goalline. (This is the worst part.) Then there is no epa cost for the penalty.
