GLENDALE, Ariz. -- The Cardinals did everything they needed to do in Sunday's 30-10 win over the Rams at University of Phoenix Stadium. They turned in complete efforts on offense and defense, they won a division game for the first time since Sept. 9, 2012, and they even got a little help from the Saints in the playoff race. But the road to the postseason is still long, and it got a little longer when play-making rookie safety Tyrann Mathieu went down on a third-quarter kick return with what the team believes is a season-ending ACL tear. Mathieu took to Twitter during and after the game to express his feelings. Playing without Mathieu will be another in a long line of tests for the Cardinals this season. Now for the particulars from Sunday's crucial win. TURNING POINT Take your pick. It was either that phenomenal 10-play, 80-yard drive Carson Palmer led right before halftime to give the Cardinals a 14-3 lead -- one series after Jim Dray fumbled at the half-yard line to keep Arizona from taking early command -- or it was Karlos Dansby's pick-six on the second play of the second half that all but put the game on ice. OFFENSIVE MVP The offensive line: OK, we could have picked receiver Larry Fitzgerald (12 catches on 12 targets with 96 yards and a TD) or Palmer (27 of 32 for 269 yards, a TD and the second-highest completion percentage in Cardinals history at 84.3), who didn't need a lick of practice time last week, but we gave them some love on Sunday, and none of that happens without the line turning in probably its best game of the season. The Cards gave left tackle Bradley Sowell plenty of help, and they built a game plan of shorter passes and even trick plays that took into account Palmer's injured elbow, Michael Floyd's bum ankle and the Rams' fierce pass rush. The result was an efficient 369-yard performance and the team's first division win in its last nine tries. DEFENSIVE MVP Karlos Dansby: Dansby led the team in tackles with eight, had a pick-six, a sack, a QB hurry and a pass defended, and leads the NFL in solo tackles with 100. What more does he need to do to earn his first Pro Bowl trip? THREE THINGS WE LEARNED The Cards have figured out how to help Sowell: On the first play Sunday, Sowell got shoved back into QB Carson Palmer as he threw, but Palmer still completed a pass to Larry Fitzgerald. From that point on, Sowell held up OK, but there was a reason. Whether it's a tight end assigned to his side or a running back left in to chip, Sowell is getting a lot of help. He still allowed some pressure, but the Cards may be able to manage with him the rest of the season before finding a replacement in the offseason. Jay Feely isn't perfect: Entering Sunday's game, kicker Jay Feely had only missed two field goals all season -- one from 50 yards and one that was blocked. On Sunday, he missed from 50 and 25 yards, dropping him to 22 of 26 for the season. The Cardinals made progress on third downs: Executing better on that key down was a focal point last week. The Cards entered the game converting just 33.3 percent of their third downs, a rate that was tied for 30th in the NFL. They converted 8 of 14 on Sunday (57 percent). Mission accomplished. INJURY REPORT S Tyrann Mathieu sustained what is believed to be a season-ending ACL tear in the third quarter while returning a free kick after a safety. ODDS AND ENDS -- Floyd was limping noticeably at times during the game on a bum ankle that limited his practice time last week. That made Fitzgerald's performance all the more impressive and important. The Cards will need Floyd down the stretch in their playoff push. -- Carolina's big loss at New Orleans helped Arizona's playoff hopes. If Dallas losses to Chicago on Monday night, the Cardinals will be all alone in seventh place in the NFC, one game behind the Panthers and 49ers for a wild-card spot. They would win a two-team tiebreaker with the Panthers based on an earlier win over them this season. -- The last time these teams met, Rams TE Jared Cook had seven catches for 141 yards and two TDs. On Sunday, he had three catches (six targets) for 49 yards. -- Patrick Peterson quietly had a terrific day in coverage that was so tight the Rams rarely even looked his way. It's a huge benefit when your top corner can take a receiver out of the game. -- "Next man up" is a familiar mantra for NFL teams besieged by injuries. But how about Rashad Johnson coming into the game after Mathieu's injury and getting a fourth-quarter pick that set up the Cards' final TD? -- John Abraham has 11 sacks in his last seven games. It's hard to believe he wasn't a starter when the season began, only gaining this opportunity when Sam Acho and Lorenzo Alexander were injured and lost for the season.UP NEXT At Tennessee, Sunday at 2:25 p.m.: The Titans (5-8) blew a big early lead in Denver on Sunday and lost big, 51-28. That loss all but ended the Titans' playoff hopes in the weak AFC wild-card race. Will that letdown help the Cardinals? Tennessee is playing without starting QB Jake Locker (foot), who is out for the season, but Ryan Fitzpatrick is no stranger to the starter's role, having held it in Buffalo for a long time.
