Question about Travis Hunter

Ok, so the Travis Hunter hype is about him playing both sides of the ball but Ive heard he is neither the best WR nor the best CB in college football. He could play both in the NFL but let's be real, it's a really difficult league that you need to pick a position and focus all your preparation on it, and not even Deion Sanders himself played a ton of WR. If teams saw Hunter as a CB or WR then why wouldnt they just pick the best WR or CB in the draft?
