While Panthers coach Ron Rivera believes a strong finish is crucial for his team’s confidence heading into next season, he’s not sure if winning three of the last four games will save his job. ‘‘I think we have to keep going,’’ Rivera said. By that he means it’s important the Panthers beat Oakland and New Orleans to finish the season 7-9, which would better last year’s record by one game. Carolina enjoyed its first blowout win Sunday, crushing San Diego, 31-7. The Panthers are 4-4 since owner Jerry Richardson fired GM Marty Hurney following a 1-5 start . . . The Jaguars (2-12) clinched their spot as the worst team in franchise history with a 24-3 loss at Miami, the team’s seventh defeat by 16 points or more this season. First-year coach Mike Mularkey insist no one is quitting, although the Jaguars have been outscored, 26-0, in the third quarter of the last three games. Jacksonville plays host to the Patriots Sunday.
