I'd rather have Campbell over Iupati at 17, and ill explain why.
first off all, Iupati is a Guard. if he didnt play Tackle in college theres no way he plays tackle in the pros. NONE. Secondly, against top flight competition in the senior bowl he had a sup par game by all accounts, gets caught holding far too often as well. also in a deep, deep draft as this, theres no way any team should be drafting a guard with a pick in the teens.
Campbell has better mobility than Iupati, and can play T. His technique is questionable, so if he fails to perform as a T, you put him inside at Guard and watch him maul people. I know Iupati is strong but Campbell is a beast, and more versatile. I think if the top tier T are gone by 13, we take BPA at that spot and take Campbell at 17 or move down if we think we can grab him later on.
