He may. Like all draftees but.....Knevitt looks like being a wasted decent pick the way he is tracking atm.
He has already shown he has good pace, when placed near the action he gets involved and best of all he us very good in the air.
You dont lose the skill...its confidence lost while learning how to play a new role that is hiding his strengths. He will take some time to develop. As his chicken legs grow in the gym he should move closer to an inside role or marking forward and he will have a bigger and more sustained impact. I hope he gets the time.
