5. Kordell Stewart‘s mad dash – Oct. 5, 1997
If it weren’t bad enough that thousands of Steelers fans had essentially transformed Memorial Stadium into Three Rivers Stadium South, the Ravens blew a 21-point lead in what proved to be the start of a six-game home losing streak to Pittsburgh.
Leading 21-0 early in the second quarter and then 24-7 at halftime, the Baltimore defense surrendered 28 unanswered points — including three touchdown passes by Kordell Stewart — in the second half to crush what had previously been a feel-good day on 33rd Street.
Though Vinny Testaverde tossed a 10-yard touchdown to Derrick Alexander to bring the Ravens back to within three in the fourth quarter, Stewart’s 74-yard sprint to the end zone sealed it for Pittsburgh, sending Baltimore fans home in a sickly fashion after a 42-34 defeat.
