There's no doubt Harbaugh is a very good coach, but it also helped Harbaugh having Taylor on his team for four years as he knows Taylor's strengths and weaknesses. This was the worst I've seen Taylor look in a Bills uniform so far. If Taylor plays this bad again, you could say it's a great coach that game planned well against him. But if he doesn't, then I think it's a combo of Baltimore knowing Taylor very well, plus Taylor's nerves of playing against his old team.
