A quick take on the Jets' upcoming opponent, the 49ers (2-1):

1. The 49ers will arrive at MetLife Stadium after a brutal 24-13 loss to the Vikings -- arguably the worst loss under Jim Harbaugh. They allowed 146 rushing yards (the previous high under Harbaugh was 124) and committed three turnovers (previous high: two).

2. To help get acclimated to East Coast time, the 49ers went from Minneapolis to Youngstown, Ohio, where they will practice for the week. They did the same thing last year after a win in Cincinnati, and they wound up rallying to beat the Eagles in Philly.

3. QB Alex Smith had thrown a franchise-record 249 straight passes without an interception before tossing a late pick last week. That's pretty impressive, considering some of the quarterbacks that have played for the Niners. Montana, anyone? Young?

4. The 49ers excel in two areas causing problems for the Jets: They can run the ball (No. 7 in rushing, 141 yards per game) and they stop the run (No. 8, 91 yards per game).

5. The 49ers are 9-2 all time against the Jets, including 5-1 on the road.

6. Darrelle Revis' season-ending knee injury means we don't get to see another Revis-Randy Moss battle. They developed quite a personal rivalry between 2007 and 2010, with Revis famously calling Moss "a slouch." According to SFGate.com, Moss was disappointed to hear about the injury. “I’ve always been a fan of Darrelle Revis," he said. "I’ve always liked competing against Darrelle Revis ... I’ve always put him in an upper-echelon class of cornerbacks, if the not the best cornerback in the league.”

7. Smith has more weapons now that they've added Moss and former Giants WR Mario Manningham, who join RB Frank Gore, TE Vernon Davis and WR Michael Crabtree. The Jets tried to trade for Crabtree during his rookie holdout in 2009, and they were accused by the Niners of tampering. They were exonerated.

8. The 49ers' defense, led by LB Patrick Willis and DE Justin Smith, is stacked. It might be the best in the league.
