Mac has got to fix this and fix it soon. Ditch the offense if is doesn't fit the skill set of what you've got. Del Rio and this OL needed or needs a FB, period. Even Meyer had to figure that out in 2006. Figure out who is going to play. But if you're keeping the shirt on Franks, figure out what AA and Trask need from a skill set. You can keep portions of your shotgun spread offense. BUT IF YOU HAVE NO THREAT OF A RUNNING QB, the deception is gone. No matter who it is you know the following:
The OL is getting better but it needs all the help it can get.
A RB would love to have an extra blocker.
Hard to block 6 with 5.
The QB does need a bit more time to get the ball to AC, TC, etc.
Like I said, a lot of this would be helped with a FB. You can still run a wide variety of your offense installed. We're at a point that it's time to just play basic football. We are way beyond the juncture that something has got to be done to help the players you have now. So Mac get it done!
