Which defensive prospect would you rather draft?

Quarterback is the glowing neon sign of offensive needs and there is no clear direction there - lots of risk with whatever direction we take at that spot.

This is the year Pace needs to throw some real skin in the game. He needs to get a QB which will have the effect of bolstering or burying his identity as a GM.
 
He doesn't have a lot of great options though he is in a better position than many other team's in the league in that he's got a top 5 pick in the draft AND he's got a few FA candidates he can grade and choose from. 

I think the other offensive needs are important but not as urgent as the QB position or the secondary.

If we're solely looking at TE, the knee injry to Jake Butt might be a blessing in disguise as his draft stock will plummett and we might be able to land a decent TE in the 3rd or 4th round. At the same time, if Pace initially has a good grade on David Njoku, he could have just elevated his status enough to make him unreachable for the Bears with that Butt exit. 

This does not seem to be the year of the OT. Even Cam Robinson - the early consensus OT - is hailed more as a mauler RT / Guard type prospect who can hold up in coverage at the college level butmight face some serious issues there at the next level. We'll see. 

WR is probably getting shuffled off to FA acquisitions. 

Yep. I know he's thrown some more INT's this year, but when I watch the kid in a big game he constantly shows up and balls out. Thats the kind of player I want. Plus as you stated he creates a ton of headaches for a defense because when nothing is there he can tuck it and create on his own. I like that he doesn't look to do that first too. He can make every throw you ask a QB to make...to me he has it all. He needs to get a little better with the deep throw, but thats nit picking.
