Upon Further Review: 49ers Week 8

A review of four hot issues from the San Francisco 49ers' 42-10 victory against the Jacksonville Jaguars in London on Sunday:

49ers are rolling: The 49ers ended a 10-day road trip in style. They thrashed winless Jacksonville in London. This game was never in question as San Francisco led 28-0 in the second quarter. Last Sunday, the 49ers led the Titans 24-0 at one point. San Francisco has won five straight games and is 6-2 at its bye. The 49ers have scored at least 31 points in every game during the win streak. Sunday was an all-around great day for the 49ers. Kansas City improved to 8-0, so a third-round 2014 draft pick became a second-round pick to complete the trade of quarterback Alex Smith. The 49ers ended up with two second-round picks in the deal. It’s a win-win.

Trade deadline looms: Will the 49ers make a trade? The NFL trade deadline is 4 p.m. ET on Tuesday. They have been rumored to be interested in receivers for weeks. Still, it is unlikely a trade is made with Michael Crabtree and Mario Manningham returning. The NFL Network reported the team is willing to deal backup running back Anthony Dixon. He is a free agent at the end of the season. The 49ers likely wouldn’t get much in return for Dixon. He is a key special teamer and might be the new kick returner. Kyle Williams was benched Sunday after a miserable game.

Kaepernick is explosive: For the second straight game, 49ers quarterback Colin Kaepernick made big plays with his legs. He had 69 yards and a touchdown on 10 carries at Tennessee. Sunday, he had 54 yards and two touchdowns on seven carries. The 49ers are opening up Kaepernick in the ground game as the season goes on, and that’s dangerous for opposing defenses.

Greg Roman sends message? San Francisco's offensive coordinator Greg Roman had a great night calling plays on Sunday. It was varied and aggressive. The Jaguars’ defense had no answer. It could serve as a retroactive reminder to first-year Jacksonville general manager David Caldwell, who didn’t wait to interview Roman for the Jaguars head coaching job when the 49ers went to the Super Bowl, even though Roman and Caldwell were college teammates. Caldwell went with Gus Bradley. It seems it’s just a matter of time before Roman gets the head-coaching call somewhere.
