Okay so, I'm looked at some of the first half plays again an have been reading some interesting analysis from guys who actually watch tape.

The creative first plays were essentially a different offense than the Jags have used all season. It was more West Coast, reflective of the Kansas City Chiefs designs by truly forcing the defense to defend the entire field East-and-West. That worked very well. Apparently those sets were newly installed over the past few weeks to put a team like New England on it's heels, and the Jags simply ran out of plays because you cannot introduce that much stuff in a few weeks

So the question that begs, is why have the Jags not used that style all season if that was in their bag of tricks. To run that system, you need an accurate QB who will make quick decisions and go through progressions. That is not who Bortles was to start the season. He really developed into that as the season progressed, but it got really difficult to completely adapt the offensive system on the fly with limited real in-season practices in today's CBA and with the rotation of injured WR's and RB's, and even to some extent the O-Line towards the end of the season.

So if they simply ran out of plays out of those sets, they then just went back to what they had been doing before, but the middle of the line could not execute a power running game in the 2nd half because the Jags don't have an elite power-block offensive line. I think gong forward to next year, moving to a more balanced and spread out system has to be the goal no matter what.

If Hackett stays, the off season should be adding more of those spread packages into the offense to give it balance and trust that Blake can be what he was in the playoffs.
If Bortles is let go, you have to bring someone who they trust to run that style of offense.
If Hackett is let go, they have to bring in someone with creativity on offense.

Most likely I think they try the first option of keeping both, and trying to get some more consistent play makers.
