But there's a big difference between regular season and post-season. A regular season loss is a bump in the road. The playoffs are where wins are vital.
Raiders already redeemed themselves in second games where they had lost the first (KC, San Diego). Same thing last year with the Jets, losing game 16 then winning the next week. That Niner game was an eon ago.
But the Niners won't even make it to the Super Bowl, so the Raiders won't get their rematch.
