He threw 3 TDs and 4 INTs in 4 postseason games that year, he was fortunate for some great matchups and excellent play from his D.
and imagine if he had a real NFL defense in his prime seasons....
He did, his D's were more than good enough to win many SBs if the QB played like he did in reg seasons but that didn't happen. Indy lost more postseason games b/c of the QB than b/c of the D.
