SAN FRANCISCO -- A few thoughts on the San Francisco 49ers' 34-3 win over the Houston Texans on Sunday night:What it means: The 49ers are making folks forget about their follies of Week 2 and Week 3 in losses to Seattle and to Indianapolis. The 49ers were outscored 56-10 in those games. Since then, they have outscored the Rams and the Texans 69-14. The 49ers are 3-2 and looking very much like a serious playoff threat again. Sunday was a great all-around day for the 49ers.
