Taking Smith in the first round (trade down or not) is a treacherous move for a GM that needs contributors on defense right now.  

 

If they are gonna' go LB in the first - I'm a little more inclined to go with the guy that could spell Poz on passing downs early in the season (and provide depth for Telvin as well.) 

 

Smith could replace Poz in 2017 completely IMO, while Jack has a few more question marks (in my mind) in terms of being a three down MLB.  Not saying Jack won't become that type of player, but he may be more suited to Telvin's role whereas Smith is equally suited to the middle as the outside.  That's my early take having just watched a few cut-ups. I'm no expert on either of these guys. 

 

If the Jags sign Weddle and a better than average pass rusher in free agency, then I wouldn't hate either pick.  Especially if a trade down for Smith produces a bounty of picks. 

 

W/O the luxury of that type of free agent haul, I'd have to say take Jack or the best defensive player available at #5.  An injured first rounder is too much of a luxury for the Jags this year without free agents that will contribute substantially and immediately.
