Fumbles lost in calculate player stats: aborted snap issue

[guga31bb]

We need to add checking for who actually fumbled like we now do in clean_pbp()

nflfastR::load_pbp(2020) %>% 
  filter(rusher_player_name == "M.Stafford" & fumble_lost == 1) %>%
  select(desc, rusher_player_name, fumbled_1_player_name)

# A tibble: 1 x 3
  desc                                                     rusher_player_name fumbled_1_player_~
