Harbaugh high on cornerbacks, special teams
Cornerback play and special teams coverage were on the top of coach Jim Harbaugh's happy list Monday.Both units came up big in the San Francisco 49ers' 34-3 win over the Houston Texans on Sunday night.Tramaine Brock, the No. 3 cornerback, had two interceptions, including one he brought back for a touchdown. Special teams suffocated Houston just as it did last week on the road against the St. Louis Rams. The group is much improved from last year.
