The first rule for getting out of a hole: stop digging.
This wasn’t a pretty win nor was it a close one the team had to sweat out. LSU took the lead early, then slowly asserted its dominance more and more, until Vandy was hopelessly behind. LSU stopped digging the hole.
The Tigers’ first four drives of the game all ended at midfield or better, but only resulted in 14 points. Being up by two touchdowns is better than being down by two touchdowns, and if your biggest problem early on is your lead isn’t big enough, then that’s one of those good kind of problems.
