It really is almost inconceivable that he could throw for 600+ yards in one week and then immediately pull a 180. There’s plenty of explanation for why LSU was prepared but you can’t just entirely luck into that type of performance. It seems like at the first sign of adversity he lost 100% of his confidence, and is now reading everything wrong. He’s throwing to the check down like it’s his first read, throwing into triple coverage, and the cherry is the throw three yards down field when he could walk to a first down. He’s got the QB yips.
