There is no way that going for a TD instead of a FG is even close to correct in that spot. You're giving up something like 2 points in EV, with a full half to play.
Not if you think your FG conversion is >70%. Which it for sure is from 41. You really think a mini-hail mary for 6 with a sub 10% success rate beats 3 points with likely >80% success rate before the end of the 1st half down 21?
EDIT: That 10% success rate is very generous also. If you only have to protect the endzone it's probably well under that.
I assume he means the screen play call which practically never gets in.
Kicking the field goal is obv correct from the 20, despite being down 21. Still a half to go. BB has been known to do some things at half time. Couple of stops (unlikely) and then you never know.
