LONDON -- A few observations from the San Francisco 49ers' 42-10 win over the Jacksonville Jaguars at Wembley Stadium in front of more than 83,000 fired-up fans.What it means: The 49ers are focused bunch. Sure, a blowout over a now 0-8 team may not be considered impressive. But it was a solid win for San Francisco, which now has won five straight. This was an ultimate trap game. The 49ers went out of their way this week to talk up Jacksonville.
