There is simply not a ton of reading going on with Keenum. I only say this after actually watching him through three games. Keenum is not seeing a ton right now. He generally goes to 1 read. While it's true he might read the defense at the Los scrimmage and change plays...while the play is in motion Keenum rarely takes time to actually read how the play is unfolding
This was true in Tampa as well and as you say could be seen in the Hawks game. If any of you get the all-22 I suggest you watch it. I think a lot if that is a function of Keenum being very careful with the ball and not a ton of confidence in his arm.
The Rams leave a ton of plays on the field between the drops and Keenum's marginal play. I used to think that as long as Keenum played ok maybe the Rams could be more than a 7 win team. However, as his sample size has gotten larger I am less convinced of that.
I wish I could take Keenum's knowledge of the playbook and insert it into Goff's brain. Keenum's ceiling appears to be 190-250 yards and 2 TDs a game. The Rams will need more than that here shortly.
