re: Why is everyone saying LSU went prevent?

Yes LSU played prevent up until the last play. Prevent also doesnt just refer to the dline genius. The fricking CBs were giving up so much space because Chavis was scared as frick of giving up a big play.

Then when he realized his foolishness, he chooses to blitz against a notoriously good screen team on 2nd and 10.

Sounds like full on herp derp by Chavis to mw.
