The Jaguars were an offseason darling but now they have become a regular season disappointment.

Following Sunday's 33-16 loss to the Oakland Raiders, the Jaguars are now 2-4 and have pushed back their hopes of reaching .500 even further.

The Jaguars haven't played like a winning team - and to make matters worse - opposing teams have thrived where they've otherwise struggled against other opponents.

The Raiders had the worst defense (statistically) in the league entering the Week 7 matchup. Against the Jaguars, they allowed just 16 points. Oakland was also ranked last against the pass, but seemingly shut down wide receivers Allen Hurns and Allen Robinson. The Raiders allowed a garbage time touchdown and picked off two passes.

This Jaguars team is faltering and they are doing so by allowing their opponents to excel with their own weaknesses.

That was one of the many takeaways from the Jaguars' loss to the Raiders. Here are 10 more:

1) This Jaguars team is undisciplined in every aspect of the roster. Blake Bortles' decision-making has been very questionable, penalties are stacking up like Monopoly money (13 fouls for 122 yards) and silly mistakes are becoming more and more evident with each loss. The Jaguars had not one, but TWO players ejected from the game against the Raiders.

Malik Jackson had three penalties for 45 yards (what?) before he was "disqualified" and Jalen Ramsey got escorted off the field for fighting. This is a professional game and the Jaguars didn't play their part.

2) Blake Bortles isn't playing like a franchise quarterback. Bortles has slumped throughout the year. There was talk of a potential turnaround last week, but he really just hasn't been good. The question is no longer "How do you pay him after these performances?" but is now "Who should his competition be next year?"

Bortles has thrown nine interceptions in six games. He is also making some poor decisions, even when his offensive line gives him time. He has held this offense back at times.

3) Allen Robinson hasn't been a factor (in a positive light) over the last two games. The Pro Bowl wide receiver has taken a step back. Never known for dropping passes, Robinson has had multiple drops in two-straight games. He was held to nine yards on two catches against the Raiders. It was his worst statistical output since his NFL debut against the Philadelphia Eagles in 2014.

4) The Jaguars once again failed to get off to a fast start. It wasn't without trying this time though. Bortles threw a pick in the end zone on a pass to Marqise Lee. This started the trend of the Jaguars stepping on their own toes in the redzone (at least for this game). The Jaguars went 0-for-3 in the redzone in the first half. They settled for just six points in the first two quarters.

5) The Jaguars made it a point to get Julius Thomas more involved early on. He was targeted six times in the first half but only produced two catches for 11 yards. There was a lot of talk about his effectiveness in the Jaguars offense. His work on Sunday - even with a garbage time touchdown catch - won't silence those discussions.

6) While Derek Carr finished with just 175 passing yards, he did go deep against the Jaguars' Cover 3 early on. The 56-yard strike to Michael Crabtree was an exceptional throw by the third-year player. The Raiders tested the Jaguars cornerbacks often and won more than lost. Crabtree beat Jaguars cornerback Prince Amukamara regularly, including the 56-yard completion and a touchdown catch.

7) Lee was the Jaguars' best player on Sunday and it wasn't close. Lee has been fantastic this season and Week 7's performance was probably the best game of his career. He caught 7-of-8 targets for 107 receiving yards. He also had two fantastic kick returns to set the Jaguars up with favorable field position. Lee's 29 receptions lead the team this season.

8) Jason Myers has silenced his critics. The young kicker is having a quietly great season. He was 3-of-3 on field goals and 1-of-1 on extra points on Sunday. He is 11-of-13 on field goals and has made all 12 extra point attempts this season.

9) Two major special teams blunders stick out from Week 7. The first was second-year wide receiver Rashad Greene trying to return a punt from the one-yard line, which obviously failed and forced the Jaguars to start from the 7-yard line while down 20-9 in the third quarter.

The second error was allowing punter Marquette King to pick up 27 yards for a first down on a poorly-snapped punt attempt. King ran a 4.7 forty-yard dash, but gaining nearly 30 yards on an improvised run is ridiculous. His own blockers weren't aware of his run because it was supposed to be a punt.

10) The Jaguars running game showed a glimmer of hope and then it quickly went away. Marcedes Lewis and Ben Koyack blocked Denico Autry, Bruce Irvin and Karl Joseph to open up a hole for running back Chris Ivory. He ran the ball 42 yards and got the Jaguars into the redzone. However, the Jaguars failed to sustain that success immediately afterwards. This running game is just as big of a problem as penalties and Bortles' play.
