He will always be an inconsistent thrower. He may improve some, but the first part of practice should not come as a surprise to anyone.
The problem is, BK isn't going to change his system to help BW be a better QB. BW has to get better at running BK's system. ND may continue to run the ball more, like last year, but the passing system is still going to require BW to make multiple reads and difficult throws (for him) over and over.
He can still have a great year IF 1) ND can run the ball effectively and frequently and 2) his receivers make plays for him. Too many bad drops last year and very few "tough" catches made.
BW needs a lot of help to be a great college QB, but the talent is there.
