I'm not going to repeat a lot of what I have already read, which I agree with completely, but here are a couple of thoughts:
When a true frosh plays the entire first game of the year at QB against a defense like FSU and has 60+ yards rushing without ever putting the ball on the ground, that is pretty special. Ball security always seems to be one of those things QBs in transition between HS and NCAAF learn last. They are just not used to being caught up with in a foot race, nor getting their arms whacked with authority. He never even looked close to letting the pigskin get away from him.
How many times last night did Sims get that last tough yard to move the sticks? I don't know the answer to that question (it feels like half a dozen), but one of the things that stood out to me was how physical he is. He is tall, he is nifty, he is pretty fast, BUT he also finishes his runs moving the tacklers forward. When a QB has that trait, combined with the others, longer drives will result and it is so frustrating for the defense. Sometimes the needed yards come easily in a bunch, but more often they are only gained through brute force at the end. Sims can make you miss. He can run past you. Perhaps just as importantly, he can also drag you with him.
These are two of my biggest takeaways from last night.
