Someone explain to me what makes Aaron Curry worth the 3rd pick?

What makes Sanchez worth a 3rd pick? He probably wont even play for a year or 2 if ever. 16 games dont = the 3rd pick. He should have stayed in school another year. He's too green.

Not many experts have Sanchez worth a top 3 pick. We need a LB that will start this season more than a QB on the bench.

We can get a green developmental QB later in the draft for the bench.
