SANTA CLARA, Calif. -- Scoring points hasn't been a problem for the Cowboys. Stopping teams has. They accomplished both Sunday afternoon.The key stats from Sunday's 40-10 win at Levi's Stadium: Dallas forced three turnovers, recorded five sacks and held San Francisco to 290 yards of total offense.Not bad for a team that didn't force any turnovers and allowed 35 points in each of their last two games -- losses to the Packers and Rams."If you look at us last year when we went on a streak and won a bunch of games, we played complementary football where we were able to get turnovers and they [offense] were able to make a lot of plays," linebacker Sean Lee said.
