If I remember right, while he was at OSU, due to the QBs they had on campus, the true freshmen QBs had minimal practice workouts, and Ewers had even less because he was one of the scout team's QBs. This was one of the main reason he transfered after that year.
Ewers came into a new system, without playing or even having a lot of practice in the prior two years. He might as well be a true freshman with two years of inactivity from his last HS game and his first College game.
it has not been pretty at times. But at times, it's effortless for him. I get the feel he expected more out of himself and tried to shoulder the team, but it didn't work out that way. Throws he made 2 years ago consistently, were off this year, which had/has him thinking about the throw too much and it shows. When the receiver is open, it's almost as if he's in the pocket praying "please be a good throw, please be a good throw", and we've seen how it goes. But then other times, especially when he spots someone open he didn't expect, he does his wrist flick without a second thought and nails a dime, effortlessly.
He's been up and down for sure, and it hasn't been pretty. A lot of it has been on him, but there's been plenty of times when the receivers haven't done him any favors, added to an O-line that's had it's share of breakdowns. Yes he could've played a little better... Or he could've played worse. It's possible he's still banged up. I remember Colt's sophomore year, his shoulder caused issues with accuracy and under throwing the deeper routes.
I think Ewers will be okay next year. He did leave the door open for competition with Arch though, so if I'm mistaken, we have another top QB recruit to lean on.
Training camp is going to be interesting next year.
