If we thinking "any position" at defense for that pick, I want somebody who plays close to the ball if I'm looking to fill that spot.
In real life, if the best player they've evaluated and feel comfortable drafting is a DB, DL, LB take em. Take the best player on their board. That first rounder gotta contribute this year, especially if most of the guys at the position will be JAGs or slightly above.
I'd feel comfortable with Jackson at the spot if the DL isn't there. Just need the guy to be a player!
