Texas on Friday night, Tampa Bay tonight: both teams were driving late, trailing, and got to 2nd down in the red zone needing only a single yard--to either score (Texas) or move the chains (Tampa Bay).

Neither team ended up getting that yard, and both teams lost.

Chunk plays matter, and scoring matters most, but short-distance conversion downs are among the most vital components in an offensive game plan--and among the most scrutinized when a close game is lost.
