I think i'm in the minority. I don't really like Smith much. I'm not saying he will bust. I just don't think he's someone who you build a defense around. I don't think he's as good as Jack but he might be drafted earlier due to Jack's injury.
For a 4-3 D, I think it only makes sense to take a LB top 10 if there's a likelihood of that LB being a focal point of your defense. Usually that's a MLB but sometimes a Von Miller or Eric Barr comes along and you make an exception. I think Jack is in that category and Smith isn't.
Myles Jack is an alpha. He's born for war. He's Dez. Jack's mentality is to go thru people. Smith's is to go around them. Jack jacks people backward. Smith is more of a drag down tackler. Both are great in coverage but Jack could probably play S. As we get closer to the draft, I'm betting there will be more anonymous scouts whispering comparisons of Smith with guys like Donnie Edwards or Derrick Johnson or maybe Karlos Dansby. Good players but not focal points. Jack, if he's up around 240-245, can be a do-everything MLB you build around.
This draft looks kind of similar to 2008 where Jerod Mayo and Keith Rivers were top 10 picks.
Rivers went 9th to CIN = Smith
Mayo went 10th to NE = Jack
