I see Carmichael's biggest issue is trying too hard the diversify the offense thinking he has to use all of his players, especially at RB. Perhaps it's his script. A perfect example was our first possession of the 2nd half.

1st & 10 Kamara off left tackle for 7 yards
2nd & 3 Jamaal Williams off right guard for 2 yards
3rd & 1 Jamaal Williams (again) up the middle for no gain
4th & 1 we are forced to punt

What the hell? Feed the ball to Kamara as long as he's moving it. We just came out of the halftime and Kamara is fresh. What's the point of bringing in Jamaal at that point? Carmichael far too often abandons what is working to stick to some sort of script at the beginning of games and the second half. I can see scripting until you find a successful tendency at the beginning of games, but use what you learn. Be flexible.
