I'm going to have to see this scheme with Stewart in it a little more before I agree with this point. I believe if anything, having both Williams and Stew in there makes the play go. (Not a great example, the but the most success we've seen with this type offense was with them against the Bucs last year) So if Williams were injured, I believe the read option would struggle as you say when we didn't have Stew in there. Ultimately, from what I've seen, I have to say this play is best used sparingly.
Yet let me ask you this question. If Andrew Luck was our QB, would we still see the read option for 50% of our plays?
We avg 200 yard rushing and 30 pts this year with Stewart. We had one of the greatest rushing attacks in league history last year with Stewart getting more reps.....there is more evidence of it working well than just that Tampa game.
Deangelo added in makes the attack all time level great....with just Stewart it would be a les flashy steady machine.
Andrew Luck is big and athletic.....he isn't a comparable runner to Cam bc of a 40 time. Luck also has a fantastic short game in regards to accuracy....and Cam's short game is his legs. Color has nothing to so with it.....skill set does.
