Good point. I do feel like I saw numerous 'glimpses' of what they were trying to do on offense throughout the year. At times the O-line was beyond stellar in pass protection, receivers this year were much better, and Allen's improvements were glaring.
But as for production, and to your point, the results(points) were not consistent. The biggest reason for this IMO is because Allen still needs to improve route timing. Secondly adding one more receiver will also help. I was actually talking about the wild card game earlier today and came to the consensus that the Duke Williams "drop"/inability to come down with the touchdown on the drive that stalled via JJ Watt sack WOULD have likely changed our perception 100% about how the offense performed. So to me, that shows just how close this team is to being the legit power house we want to see.
