The offense is going to be much better next year because it will be much more consistent. They have to develop depth at the QB position because injuries with this style of offense. The line will be better. They shouldn't lose anyone of significance on offense to the draft or transfer.
The defense is another story. They have some pretty good depth but It could face another year of early draft departures. I don't think any of them should leave but I am sure that some will go.
Kelsey-gone as long as his injury doesn't prevent him from working out.
Fields-playing really well. I love for him to stay he could up improving his draft status tremendously.
Clemons-don't see it but he will probably go.
Brown-another year could really raise his draft position.
Young-not ready
Wiggins-too small for high pick in NFL.
That is a lot of talent to replace. Fields would be very hard to replace production wise.
