FORT WORTH (CBSDFW.COM) – The Cowboys have an obvious need at offensive guard. The unquestioned top OG in this NFL Draft is Stanford’s David DeCastro, who performed as advertised at the NFL Scouting Combine on Saturday. He may very well be drafted before the Cowboys pick at #14.

If DeCastro is available at 14, a question the Cowboys have to answer is do they want to spend a 1st round pick on an offensive guard, normally not a premium position, or can they find a starting OG to their liking either later in the draft or in free agency?

Some Scouting Combine O-Line observations:

David DeCastro – OG – Stanford – 6-5, 316: looks like he’s a no-nonsense throwback interior offensive lineman who will play at a Pro Bowl level over the next decade….benched 225 pounds 34 times…said to have a 20-inch neck, non-stop work ethic….would be a rock solid pick.

Cordy Glenn – OT/OG – Georgia – 6-5, 346: ensured himself a whole lot of money at this combine….a mammoth, versatile behemoth with 35 ¾ inch arms who had 31 bench reps and was amazingly light on his feet in drills….made 50 career starts at Georgia, 32 at guard, 18 at left tackle…his performance may have moved him to mid-1st round where the Cowboys pick…while DeCastro is strictly an interior lineman, Glenn has position versatility which adds to his value. The Cowboys could play Glenn at guard, and if they had an injury at tackle, move him outside.

Amini Silatolu – OG – Midwestern State – 6-3, 311: yes, that’s right, he’s from Midwestern State University, the Cowboys’ former training camp home in Wichita Falls. Mike Mayock of the NFL Network said he thinks Silatolu will be a starting guard in the NFL…he played LT in college….projects as a 2nd or 3rd round pick.

Jeff Allen – OG/OT – Illinois – 6-4, 307: projected as a 4th round pick…made 47 starts, 38 at left tackle…could play tackle or guard in the NFL…2-year captain…consistent, hard worker…winner of team’s Best Effort Offense Award…just a mid-round possibility who caught my eye.

Kelvin Beachum – OG – SMU – 6-3, 307: late round or undrafted developmental prospect…4 year starting LT at SMU but projects as a guard in the pros….he’s a practice squad player early who could develop into something once he gets into Mike Woicik’s weight program and builds his upper body (only 19 bench reps)….was light on his feet in drills, showing potential, but it’s these leadership and intelligence intangibles that make you want to give him a shot: earned economics degree at SMU with a 3.66 GPA, working on his masters…president of SMU’s Student-Athlete Advisory Committee, serves on Student Affairs Leadership Council, SMU Athletic Council, three committees at his church, and was named one of 10 recipients of the SMU’s prestigious “M” Award, the top recognition given to students, faculty, and staff at SMU for their “inspiration to others and unselfish giving” to make the university a better place….Beachum is the type person any organization would want to have.

Among those who were unimpressive for one reason or another: projected 2nd round pick OG Brandon Washington (Miami), OG Rishaw Johnson (Calif, PA), OG Rokevious Watkins (South Carolina), C Michael Brewster (Ohio State), OT Marcel Jones (Nebraska), and OT Josh Oglesby (Wisconsin).

Expect the Cowboys to select one of these players in late April. Ha!
