As I said, there was no correct call. Not only could the TU DBs not cover the LSU receivers, they weren’t really staying close to them much of the time. You are incorrectly assuming that because what they did didn’t work, what they didn’t do would have. Burrow missed 3 throws in the second half: 1 drop by the RB that caused the first 3 and out, 1 throw away out of bounds, and one actual miss. If Burrow had time to throw, he was almost certainly going to complete the pass for a first down. The blitz presented the opportunity for a negative outcome. The larger issue was the missed tackle by Texas’ best player, but even that wasn’t the worst possible outcome. The worst outcome was LSU getting the first down and scoring a minute or so later leaving Texas down 14 with no timeouts and a few seconds left on the clock. In that case, there is likely no late TD or onside kick to leave you with the feeling that you were just a couple plays short of sending the game to OT.
