All kidding aside: If the Colts are serious about competition at every position, I want to see what he can do with the first stringers. If he stinks, at least they gave him a shot. He could end up being a solid backup
It's still NOT irrelevant. Unless you think he does that 100% of the time, which he does not. Him missing dropping defenders and forcing throws are a well documented things. And those things are still a small sample of his body of work. And when he actually makes the right read and make the right throw it makes it much more likely he will be able to complete the required passes.
Think of it like this... he did have a bad season, he did force a ton of throws he shouldn't have, he was throwing to horrible receiving talent and was (not) protected by horrible OLine... and he still completed 62% of his passes. This is still about 5-6%+ higher than someone like Josh Allen who went no. 8 in the draft and had similar strengths, but nothing close to the arm talent and accuracy...
This is also still higher completion % than the master of reading the field and accuracy and decision-making in Jake Fromm, who was playing behind one of the best OLines in the country and had 5 star talent all over the field.
So yeah... arm talent matters and it is not irrelevant. Even when you make a ton of mistakes and have a horrible season, it still helps you maintain a certain level of efficiency.
Again - of course it matters. You can see it mattering all the time if you watch his tape... Just like you can see some of his poor decision making on the tape. Both matter. The question is - can his aggression and YOLO nature be reined in and channeled into a more effective and positive direction?
