Raiders vs. Titans 2015 live stream: Time, TV schedule and how to watch online

Three weeks ago, the Oakland Raiders were discussed as one of the hottest and most dangerous teams in the league. However, they have lost each of their three games since in frustrating fashion. The team looks to correct its mistakes Sunday against the Tennessee Titans.

Though 2015 has proved a breakout season for second-year quarterback Derek Carr, his play has fallen off over the Raiders' last two games. Against the Vikings, Carr continuously targeted receivers covered by cornerback Terence Newman, who picked him off twice including a backbreaking end-zone interception to seal the game for Minnesota.

Carr's next game proved even more difficult, as he completed just over 50 percent of his passes and failed to throw for a single touchdown. In particular, he seemed unable to find lead receiver Amari Cooper, who finished the game with just one catch for 4 yards.

Meanwhile, the Raiders' defense has struggled to keep opposing teams out of the end zone during over the past three weeks. The unit has allowed an average of 28.7 points during that stretch, with only the Detroit Lions failing to cross the 20-point threshold. For Oakland to succeed on defense, it needs the pass rush to cover up the weaknesses in the secondary.

However, that task became even greater when the NFL suspended edge rusher Aldon Smith for one year, ending his season and delaying the start of his 2016 campaign. The team was already playing without Justin Tuck, who landed on season-ending injured reserve with a torn pectoral muscle.

With Smith out, the burden falls on second-year defensive end Khalil Mack to lead the pass rush. So far this season, he has amassed five sacks and 48 total pressures, according to Pro Football Focus. Mack, already the target of double teams, could see even more attention from opposing blockers in the coming weeks. Still, the pass rusher possesses transcendent talent and should remain a force no matter what teams throw at him.

As for the Titans, rookie quarterback Marcus Mariota finally looks healthy after missing time earlier in the month with a knee injury. Mariota is still figuring out how to exploit NFL defenses, but his poise and athleticism make him one of the more dangerous first-year signal callers of recent vintage. Perhaps most importantly, he avoids interceptions while still taking the occasional risk downfield. On the year, Mariota has thrown 13 scores against just six picks.

To help their young quarterback, the Titans need to generate some production on the ground. That hasn't come easy this season, as former second-round pick Bishop Sankey doesn't appear to be a starting-caliber tailback. The undrafted Antonio Andrews has flashed at times, but at present he averages less than 4 yards per carry. The ground attack could get a lift this week as David Cobb is now a few weeks back into the flow following a stint on short-term injured reserve.
