Can someone please explain the horrendous performance by the San Francisco 49ers with a 21-0 loss against the supposed underdog Tampa Bay Buccaneers? I haven't followed the threads for this week, but I am assuming this game was viewed as a trap being that the public was pounding the Bucs, yet the spread remained stagnant. And all week I kept thinking why SF was even favored in the first place? Can anyone explain why the lines makers didn't budge to what seemed like a legitimate bet for the Bucs?
