I think that Clark is just hurrying it all the time, probably partially because of his smaller frame can't bust tackles yet.
Possibly, and with that in mind, he seems to lose sight of the ball where it's contested. Then does an okay job of getting over it, but not getting it out. Needs a bit more radar. They are all the hallmarks of experience, adjusting to the pace and strength and we are obviously going to be patient, with the talent he no doubt has. Think they'll extend his chance to learn on the job.
