Calls for an "immediate impact" at CB through the draft. Do they make sense?

What defense were you watching last year?

We have holes the size of canyons on defense. But you want to draft a "potential" bench sitter with our first choice.

What gives?

Unless we got Ellis or Dorsey theres not room for a rookie to come in and start unless they just have an unbelievable TC. The one exception is safety, but what safety are we going to take at 10? We pretty much filled all our holes on defense.
