Frank Gore quickly gave credit to rookie LaMichael James for an impressive NFL debut — and for taking some pressure off the three-time Pro Bowler in the process.

Anthony Dixon is doing his part for San Francisco, too.

The 49ers' versatile running game showed its depth in Sunday's 27-13 victory against Miami, with Gore leading the way en route to his sixth career 1,000-yard rushing season.

It sure doesn't appear as though Brandon Jacobs will be back in the mix the rest of the way — barring an injury, of course — after he became increasingly verbal in his frustration via social media during the weekend over a lack of playing time. He referenced being "on this team rotting away."

Coach Jim Harbaugh declined to address Jacobs' comments on Monday, even when asked whether Jacobs is still on the team. He said he was invoking his "fifth amendment" right.
