The Arizona Cardinals finally have their first victory <a title="" href=""></a> , but plenty of problems remain.Arizona (1-4) scored three touchdowns off five San Francisco turnovers on its way to a 28-18 road victory on Sunday.The season-high five takeaways mask a lot of things that didn't go so well, not that Arizona will complain about getting first-year coach Steve Wilks his first victory."I felt good for everybody because the coaches, as well as the players, have been working so hard to try to get this win," Wilks said on Monday.The Cardinals' offense started out spectacularly. On Arizona's first play, a pair of rookies 鈥?Josh Rosen and Christian Kirk 鈥?connected on a 75-yard touchdown. But the rest of the game, the Cardinals managed just 145 yards."Again, inconsistencies," Wilks said. "When you look across the board, it's not just one guy. Everybody's taking their turn at making that one mistake <a title="" href=""></a> , which is really costing us as far as having a big play here or there, whether it's a drop by a receiver, a lineman not executing their block, a running back not hitting the right hole, whatever it may be."Rosen had a sputtering afternoon in his second NFL start. He finished 10 of 25 for 170 yards. That's 9 for 24 for 95 yards after that opening 75-yard pass."Josh is going to be a work in progress because you really can't get it done in practice," Wilks said. "You show him the different looks, but those guys are going at a different speed on game day. So he's going to learn on the run. He's going to have to have a few bumps here and there, but he's going to also make some good plays."Arizona was on the field for 92 defensive snaps, the Cardinals' most since 1958."We've got to do a much better job of getting off the field," Wilks said. "They had a 13-play drive I believe in the third quarter <a title="Authentic Ben Gedeon Jersey" href="">Authentic Ben Gedeon Jersey</a> , and they only had one third down. So again, we've got to create negative plays and get these guys in third-and-long and get off the field."Chandler Jones certainly did his part.The big defensive end had six tackles, a sack, two tackles for loss, two quarterback hits, a fumble recovery and a pass defensed."Yeah, that was a lot of plays," Jones said after the game. "That was a lot of reps. We just tried to capitalize."Jones has at least one sack in 26 of 37 games he's played with Arizona.The Cardinals play at Minnesota on Sunday.Notes: Arizona has signed WR Kendall Wright to a one-year contract and released CB Deatrick Nichols. Wright is a six-year NFL veteran who has played in 82 games with 339 receptions for 3,858 yards and 19 touchdowns. The Buffalo Bills unfolded an astute defensive game plan at Minnesota and unleashed their front seven on Vikings quarterback Kirk Cousins.The most important part of their preparation and execution? Forcing Cousins to fumble.With a third-down strip-sack of Cousins inside the 20-yard line to turn the ball over on each of Minnesota's first two possessions, Buffalo converted those big plays into 10 easy points on the way to a 27-6 victory Sunday."We drop back every single day and talk about having two hands on the ball and protecting the football and understanding how important that is <a title="" href=""></a> ," said Cousins, who also threw an interception.Since Cousins became a full-time starter for Washington to begin the 2015 season, he has fumbled 33 times. That's one behind Seattle's Russell Wilson for the most in the NFL over that span. Cousins has lost 13 of those fumbles, including the pair in the first quarter on sacks by Jerry Hughes and Trent Murphy . Lorenzo Alexander and Matt Milano, who picked off the bobbled pass in the third quarter , recovered them.According to Alexander, the defense made Cousins a prime target for prying the ball loose in meetings during the week."With guys like Jerry and Trent coming in from behind, they just don't have the awareness that a running back or receiver would have," Alexander said. "We're always taught to strip the ball because sack fumbles are game-changers."With Vikings running back Dalvin Cook held out because of a hamstring injury and the Bills ahead 24-0 with less than three minutes elapsed in the second quarter, the pressure only increased on Cousins and his offensive line. The Vikings attempted a franchise-record six rushes <a title="Womens Eric Kendricks Jersey" href="">Womens Eric Kendricks Jersey</a> , two of which were scrambles by Cousins. He finished 40 for 55 for 296 yards, including a late touchdown pass to Kyle Rudolph ."Our secondary has been doing a fantastic job of making the quarterback hold the ball for us," said Hughes, who dominated left tackle Riley Reiff throughout the game and had two quarterback hits.Milano and Kyle Williams also registered sacks. The Vikings had only 46 yards at halftime."They're a good defense," Reiff said, "and it wasn't fun."Head coach Sean McDermott took over the play-calling responsibility from defensive coordinator Leslie Frazier at halftime last week against San Diego, with the Bills trailing 28-6. McDermott said he and Frazier, the former Vikings head coach, were in collaboration with the play-calling this time."I want to give credit to the staff and players with getting on the same page with what we're trying to get done," McDermott said.That included a priority of pressuring Cousins <a title="Customized Minnesota Vikings Jerseys" href="">Customized Minnesota Vikings Jerseys</a> , who lost to Carolina with Washington while McDermott was the defensive coordinator there in both 2015 and 2016. Cousins threw two interceptions, lost three fumbles and was sacked six times over those previous two games."He had always given me a hard time when I played him, so I just felt that these guys were going to be a challenge," Cousins said, "and they were."
