Just curious but why is it limited to the "2nd half" of games? Did the first half of games not bear fruit on the theory?
I don't get the parsing of the stats to differentiate between 2nd half and 4th quarter (etc.) RTPs?
The only meaningful stat should be whether the foul is being called or not. When you parse the stats you're making an insinuation (baseless without actual evidence) that calls aren't being made at certain times of the game when they should.
Romo has received a disproportionately low number of RTP calls over his career since the beginning of his second season as a starter. And within that, he has gotten an even lower number of calls in the 2nd half (one), and especially the 4th quarter (zero). Maybe you can explain why you think one of those things is meaningful and the other not (even ignoring the fact that Romo is better in the 2nd half, and especially the 4th quarter).
You can look at the entire game and still get the picture (2 calls in 83 games), but it's also completely valid to point out that the call hasn't been made evenly in Romo's case with regard to the quarter or half in which it was made. In fact, given the fact that Romo is the league's highest-rated passer in the 4th qtr or OT, it would have been careless of me to ignore the fact that he has never gotten the call in the 4th qtr or OT, and the analysis would have been incomplete.
Last year, league-wide, RTP was called once every 195 attempts in the first 3 quarters and every 150 attempts in the 4th qtr or OT. That means it was
more common to get the call in the 4th qtr or OT -- not less.
From 2007-12, RTP was called for Romo once every 1,174 attempts in the first 3 quarters and
never in his 851 attempts in the 4th qtr or OT.
If you specifically want to be less specific...
Last year, league-wide, RTP was called once every 179 attempts. About every 5 games for each QB.
From 2007-12, RTP was called for Romo once every 1,573 attempts. About every 44 games.
