Jaguars receiver Allen Robinson was still sitting at his locker long after his teammates had showered, dressed and left the facility.

His emotions were easy to read following Sunday's 33-16 loss to Oakland at EverBank Field. Robinson caught two passes for 9 yards on eight targets. He dropped three passes.

What happened to the star that caught 80 passes for 1,400 yards and a franchise-record 14 touchdowns last season?

Robinson's third season has gone way off track through six games. He doesn't lead the team in catches and is third in yardage.

Robinson's average per catch is 11.4 yards. It was 17.5 a year ago.

The 23-year-old Robinson led the NFL with 31 catches of at least 20 yards last season. That was five more than any other player. He was a deep-ball superstar, capable of out-leaping defenders and securing impressive catches.

Robinson has three catches of at least 20 yards this season. There were 49 players in the league with more as of early Sunday evening.

Quarterback Blake Bortles' stunning regression isn't helping, but Robinson's drops aren't anyone's fault but his own.

"I'm pretty shocked," Robinson said. "It's frustrating. I can't focus on those plays last year. I've got to make the plays this year. I can't try to make a super play every time. I've just got to make the play in front of me."

Robinson dropped a touchdown in last week's 17-16 win at Chicago that turned into an interception.

The one that stung on Sunday occurred early in the third quarter. The Jaguars had kicked a field goal on their first drive to cut the lead to 20-9 and the defense had forced a punt.

The Jaguars had the ball at their own 7-yard line. On first down, Bortles threw to an open Robinson 14 yards downfield on a hook. He had plenty of separation to make the catch for a first down and try to get some rhythm going.

Instead, the Jaguars went three and out and punted.

"I can't press to make plays and try to overplay," Robinson said. "When you do that, it's a negative outcome. So, I've got to figure out a way to get this thing going. I'm anxious to make a play and I need to keep calm. I need to make the play when my number is called."

Part of the issue is Bortles. He threw behind Robinson early in the game. Bortles' inconsistencies have to be affecting the receivers.

"It's obviously very uncharacteristic for A-Rob to drop a ball," Bortles said. "I know from his point of view, he wants to get an opportunity so bad. He's getting doubled, he's getting safeties over the top of him…I know he's juiced up and dying to make a play. From my point of view, it doesn't matter if he drops one ball or 10 balls today, every time I get a chance to throw Allen Robinson the ball, I'm going to."

Robinson also isn't being helped by his offensive coordinator, Greg Olson. On third-and-goal from the 10 on Sunday, Robinson was asked to run a 5-yard slant. He caught it and was immediately tackled. That's a conservative route for what appeared to be the primary target on the play.

The NFL's defensive minds studied the Jaguars young, emerging offense in the offseason.

Defensive coordinators are punching and Olson isn't punching back.

The Jaguars look like they've been caught schematically and don't have an answer.

Robinson has three touchdown catches this season. They have totaled 17 yards.

"You can't teach what he has, the athleticism," Jaguars tight end Marcedes Lewis said. "It's innate traits. Just keep doing what you do and believe in it. Whether it's timing between him and Blake, the time will come. Keep believing in your process, because if you don't everyone will go in the tank. The results will come if he rides it out."

The Jaguars need their playmaker to find his form.

They also need Bortles' to find his accuracy and for Olson to quickly find solutions to get defenders guessing again.

But, make no mistake. Robinson's drops are a problem that has to stop now. He has six now on the season.

"I don't think it will hard to get him back on track," Jaguars coach Gus Bradley said. "I don't know why it happened - I know there are times when it can happen to a receiver. I'm not going to sit here and say it's because he's pressing - I don't know that. But I do know we had some guys pressing trying to make plays and creating something for our whole team and sometimes when you do that, it doesn't go your way."
