MIAMI GARDENS, Fla. – The Jaguars' starters made their 2019 debut Thursday.

The first-team offense looked good on one drive and struggled on three others in what became a loss to the Miami Dolphins at Hard Rock Stadium. The first-team defense looked really good for an entire quarter, and rookie defensive end/linebacker Josh Allen looks like a star.

Those are the big-picture takeaways. All other storylines from the only 2019 preseason game in which the Jaguars' starters will play pale in comparison.

Remember: The Jaguars' starters played just one quarter, so it probably would be best to not overreact to what we saw Thursday.

Somehow, I don't imagine that recommendation will curb the overreacting.

Let's get to it …

Josh Allen looks big on a field with other big men.

This was the much-anticipated, oft-discussed, mega-ballyhooed First Email of the Game – and it was a prophetic email. Yes, Jaguars rookie edge defender Josh Allen looks like a big man in a game played by big men. He's also a strong, fast, athletic man in a game played by strong, fast, athletic men. Allen, the No. 7 overall selection in the 2019 NFL Draft, had been very impressive throughout training camp – and he was dominant on Thursday. He had at least four quarterback pressures and two tackles for losses. He also had a pressure that led to a sack by defensive end Dawuane Smoot. While this is still preseason, there's no reason to think Allen won't have major impact. This kid's for real.

Josh Allen is looking the part.

Unbelievably so.

Very disappointing first-string offense. Lots of work to do before season starts don't you think?

Sure, there's work to do before the season. But very disappointed? No. The Jaguars' starters played for one quarter – and scored a touchdown. The first-team offense was playing together in a game for the first time. Their offensive line has been together for a week. The unit wasn't great, but it showed enough to feel OK.

Josh Allen may be special...

Yes.

I think Josh Allen proved tonight that Taven Bryan was a swing and a miss. I've never seen Taven remotely look like Josh did tonight. Hard to believe they were both top 5 picks.

That is hard to believe, first and foremost because neither were top five draft selections. But no: Bryan is not on the same level as Allen. That's not unexpected considering Allen was projected by some as one of the best two players in his draft class and Bryan was a low first-round selection.

If Fournette can keep up the effort and attitude he gave in the first half against the Dolphins, he can expel the "bad-apple" moniker pretty quickly.

Agreed. Thursday was the only time we'll see Jaguars running back Leonard Fournette in the preseason. He looked ready. More importantly, he ran hard. That's a good sign.

Adam from Wescosville, PA

I'm finally seeing that little jump cut Fournette had been missing since college.

It was encouraging.

Howard from Homestead, FL

New rule: Personal foul, 15-yard penalty for "icing the kicker" in preseason. What say you, John?

Anything that stops the clock during the preseason should be 15 yards, grounds for ejection and perhaps suspension from the NFL.

Not even halftime, but Josh Allen and Smoot looking great on D. That's going to be a very good and deep defensive line. Offensive side, Fournette looks good and looks like the talk of quarterback Nick Foles not having much help at wide receiver and tight end looks true. Outside of wide receiver Dede Westbrook, no one seems to get open for him. Hopefully, Marqise Lee helps?

Smoot is an overlooked story this preseason, but the coaches believe he has played very well in camp – and he showed up in a big way Thursday. I wouldn't sweat what we saw from the wide receivers or tight ends Thursday. The first team played just one quarter, and there's a limited about of game-specific game-planning going on. Let's let this team play a couple of real games – with the starting tight ends – before we write off the tight ends and receivers.

Jerell from Columbia, SC

Damn, Josh Allen looks to be the real deal. Against the run and pass – and oh, in coverage as well. I am a little excited.

Josh Allen made Jerell happy. He can play a long time in the NFL and never have a moment like this.
