Here's an example of play where Colin may have gained positive yards on a scramble, got a first down, but missed a better opportunity. This is where i'd like to see growth in him as a QB.
3:30 2nd QTR:

Here, we come out in "21" personnel and split Miller out wide. This gives CK an easier read on the defense. You can see it's #22 on Miller - a corner. That reveals zone coverage as that puts a LB on Crabree in the slot. No defense in its right mind will put a LB on a WR in man-coverage. So, that, mixed with the single safety, shows cover 3 zone right off the bat.

So, after gathering that information, we then motion Miller into the backfield to help sell our run fake. CK, should know that the cover 3 zone will be vulnerable over the intermediate middle.

The run fake brings the LB's up just a little - that's all you need, and it will open up the intermediate middle.

This is what Kap sees right as he turns around. He should be looking for the intermediate middle route to Crabtree the moment he turns around(as all the pre-snap information showed him that).

The ball should be out right here to this spot where the arrow's pointing. I've seen Kap do this before, but, again, it comes down to consistency. It's a small window and you have to fire this ball right on time to get it between the LB's.

If he throws the ball when I showed, he'd hit Crabs right here - open for a nice 12 yard gain. Even without that, he's got two underneath receivers open as well - doesn't throw to either one of them.

Instead, he takes off and gains 5 yards. This was 2nd and 1 - so, I understand he was looking for the big shot, but, he also needs to have a full awareness of what the defense is going to give you. The moment he turned around and saw the safety closing on the seam route, you go to the intermediate in route. Part of that process of getting the information to digest faster and get the ball out. It's a lot on him to do in a fraction of a second, but, that's what the elite QB's do.
