NT. Goal is to stop the run. 2 down player maybe, more like 1.5 downs in todays NFL. Teams win throwing the ball not by running. That's the reason QBs are so valuable.

First round and second round draft picks should be on the positions that most help you win games. QB, WR, CB, S, Pass rusher, OT.

Nose tackles are not that valuable in comparison. If you made a list of positions, prioritized by value how would go?

QB
CB
WR
Pass Rusher
OT
CB
FS
OT
Pass Rusher
WR
FS
SS
MLB--with coverage skills
....

NT is still a ways away.
