I don't think they did. That's all on the four interceptions from Purdy. A lesson needs to be learned from it. You can be sure the analysts did their best job to analyse what went wrong and do their best not to repeat it. The advantage is actually with the 49ers here, as there isn't much to analyse on the Ravens side.Didn't BAL just kick the sh*t out of them?
Remember all those times NE got their butt kicked in games and in the first half of the game, then coming back with a changed game plan to win. Remember the 28-3, to end with 28-34 after another half.
Never show them all your weapons in the regular season or first half of a game. Do it when they can't make big changes anymore.
