How to detect blocked punts recovered for a TD

[ToddAtWSU]

So I am trying to see how many "defensive" touchdowns a team has and I have the following block in a for-loop:

` numDefTDs = 0 for play in nflgame.combine_plays(week).filter(defense_frec_tds=True):

play.team shows the offense that gave up the TD

                    # so if play.team is the same as game.away, our defense got the fum rec td
                    if play.team == game.away:
                        numDefTDs += 1
                for play in nflgame.combine_plays(week).filter(defense_int_tds=True):
                    # play.team shows the offense that gave up the TD
                    # so if play.team is the same as game.away, our defense got the int td
                    if play.team == game.away:
                        numDefTDs += 1
                for play in nflgame.combine_plays(week).filter(kickret_tds=True):
                    # play.team shows the offense that gave up the TD
                    # so if play.team is the same as game.away, our defense got the kick ret td
                    if play.team == game.away:
                        numDefTDs += 1
                for play in nflgame.combine_plays(week).filter(puntret_tds=True):
                    # play.team shows the offense that gave up the TD
                    # so if play.team is the same as game.away, our defense got the punt ret td
                    if play.team == game.away:
                        numDefTDs += 1`

So I am gathering INT and fumble recovery TDs plus punt and kickoff returns and this has worked fine for the past couple years. But in the Pittsburgh/Cleveland game, Pittsburgh blocked a punt and recovered it for a TD. Is there a stat to show this? Thanks!

import nflgame

games = nflgame.games(2017, 1, kind='REG')
plays = nflgame.combine_plays(games).filter(defense_puntblk__ge=1, touchdown__ge=1)
for play in plays:
    print play

(CLE, CLE 16, Q1, 4 and 19) (12:44) B.Colquitt punt is BLOCKED by T.Matakevich, Center-C.Hughlett, RECOVERED by PIT-A.Chickillo at CLE -8. TOUCHDOWN.

Looks like there were two punt blocks for touchdown last season.

import nflgame

games = nflgame.games(2016, kind='REG')
plays = nflgame.combine_plays(games).filter(defense_puntblk__ge=1, touchdown__ge=1)
for play in plays:
    print play

(PIT, PIT 33, Q4, 4 and 8) (13:44) (Punt formation) J.Berry punt is BLOCKED by J.Allen, Center-G.Warren, RECOVERED by BAL-C.Moore at PIT 14. C.Moore for 14 yards, TOUCHDOWN.
(NYJ, NYJ 41, Q3, 4 and 12) (10:37) L.Edwards punt is BLOCKED by W.Aikens, Center-T.Purdum, RECOVERED by MIA-W.Aikens at NYJ 11. W.Aikens for 11 yards, TOUCHDOWN. Penalty on NYJ, Illegal Formation, declined.

Edit: Nevermind, figured out my bug. Thanks, this works perfectly!!

I want to amend my original answer a bit. By doing .filter(defense_puntblk__ge=1, touchdown__ge=1) you will indeed catch plays that included both a punt block & a touchdown. But those could technically include plays where the punting team had their kick blocked, ended up recovering, and taking all the way for a touchdown...I don't know if such a play would even be legal, but we can do better.

import nflgame
games = nflgame.games(year=2014, kind='REG')

plays = nflgame.combine_plays(games).filter(defense_puntblk=True, touchdown=True)
print len([p for p in plays])  # 10

plays = nflgame.combine_plays(games).filter(defense_puntblk=True, defense_tds=True)
print len([p for p in plays])  # 10

plays = nflgame.combine_plays(games).filter(defense_puntblk=True, touchdown=True, defense_tds=False)
print len([p for p in plays])  # 0

Okay, so how do I get that Pittsburgh got the TD in this?

I'm having trouble deciphering your code in that format, but aren't you already determining the defensive team in most every line in your OP (ie. # play.team shows the offense that gave up the TD # so if play.team is the same as game.away, our defense got the fum rec td)? Ignoring all that, here is one way you could do it.

def defense_on_field(play):
    if play.home:  # play.home == True if home team has the ball
        return play.drive.game.away
    return play.drive.game.home

I'm curious how using the .filter(defense_tds=True) compares to your big loop...

import nflgame

def defense_on_field(play):
    if play.home:  # play.home == True if home team has the ball
        return play.drive.game.away
    return play.drive.game.home

games = nflgame.games(year=2017, week=1, kind='REG')
plays = nflgame.combine_plays(games).filter(defense_tds=True)

for play in plays:
    print 'Defense:', defense_on_field(play), 'in play:', play

Defense: PIT in play: (CLE, CLE 16, Q1, 4 and 19) (12:44) B.Colquitt punt is BLOCKED by T.Matakevich, Center-C.Hughlett, RECOVERED by PIT-A.Chickillo at CLE -8. TOUCHDOWN.
Defense: ARI in play: (DET, ARI 21, Q1, 2 and 5) (11:29) (Shotgun) M.Stafford pass short middle intended for G.Tate INTERCEPTED by J.Bethel at ARI 18. J.Bethel for 82 yards, TOUCHDOWN.

So you're saying I can just filter by "defense_tds" and I don't have to look for all the possible Defensive TDs? Is there also a Special Teams TD or do I still need to look for kickoff returns and punt returns? Where do you see all the options you can filter plays by? Thanks again!

The wiki has a table with stat types though in truth I probably end up stumbling upon much of what I use by random inspection.

For example, in the initial code I posted to your question, printing dir(play) tells me a lot about what does and doesn't apply to that particular play.

import nflgame
games = nflgame.games(year=2017, week=1, kind='REG')

plays = nflgame.combine_plays(games).filter(defense_puntblk=True, touchdown=True)
for play in plays:
    print play
print '-'*25
print dir(play)

(CLE, CLE 16, Q1, 4 and 19) (12:44) B.Colquitt punt is BLOCKED by T.Matakevich, Center-C.Hughlett, RECOVERED by PIT-A.Chickillo at CLE -8. TOUCHDOWN.

Looking at that, I noticed the defense_tds which is probably a closer stat to what you were looking for vs. just generic touchdown.

Cool, I will look into this a little more tonight. Thanks for your help!
