2012 NFL Draft Order: Which Top-20 Sleepers Will Be the Best Pros?

Outside of two coin flips, the order of the top 20 selections in the 2012 NFL draft are set (see below). 

This year's class is absolutely loaded with instant-impact, high-profile prospects that have received a great deal of notoriety during their college careers.

But there are a few "hidden" gems that should be picked in the first-round who will become household names in the NFL.

David DeCastro, OG Stanford 

Say hello to my newest man crush, David DeCastro of Stanford. 

The can't-miss offensive line prospects are typically franchise left tackles. While USC's Matt Kalil will likely go in the top five and will be a solid pro, DeCastro is the most polished offensive lineman in this class.

Interior lineman usually don't go in the top half of the first round, but we saw center Mike Pouncey go to the Miami Dolphins at No. 15 last year, and DeCastro could have a similar fate.

He's and extremely strong 6'5'', 310-pound mauler that plays with a nasty streak. The All-American is also labeled as a technician with quick feet and ridiculously high football IQ. 

An intelligent Stanford kid, no way.

Whichever teams drafts DeCastro will instantly be more successful running the football and their quarterback will be able to breathe easier on passing downs.

Total stud that has "All-Pro" written all over him.

Courtney Upshaw, OLB Alabama 

While he's received a decent amount of publicity, Alabama's defense as a whole has been the bigger story in 2011. 

Upshaw is a fantastic OLB-hybrid at 6'2'', 265 pounds. 

He has 15.5 sacks in the last two season with the Crimson Tide and has the athleticism to work situationally in coverage and even play other linebacking positions. 

With many teams running a variety of defensive alignments, his versatility will make him a major asset as a professional. 

Maybe not a instant star, but a quality player that'll benefit any NFL defense.

Menacing pass-rushers have never been so important. 

Taking a star from arguably the nation's best defense is never a bad idea, right?
