Derrick Shelby Signs with Dolphins: Highlights, Scouting Report and Analysis

The Miami Dolphins have agreed to terms with undrafted rookie free agent Derrick Shelby, according to NFL.com.

A four-year starter at Utah, Shelby has played all over the defensive front making him quite versatile. He has tweener size at 6'3'', 265 pounds and projects to the NFL as a 3-4 OLB or 4-3 DE.

There's major upside here, as Shelby could turn into a real star if coached up properly.

Shelby has produced consistent yet modest sack numbers from the end position, but has shown a knack against the run and often ranked first on his team in tackles resulting in a loss.

What the Experts Are Saying:

ProFootballWeekly.com offers their take on Shelby's pros.

"

Sizable wing span. Athletic—exhibited some explosion and agility at the Combine. Has strength, knee bend and lateral agility to stack blocks, disengage and grab ballcarriers. Shows ability to play behind the line of scrimmage. Good balance and short-area quickness. Has played end, tackle, both the left and right side and also has rushed from a two-point stance. Four-year starter.

"

And for the sake of objectivity, the NFL.com's argument for Shelby's weaknesses:

"

Despite his playing experience, it is scary at times when grading his ability to diagnose plays and make quick decisions on the line. Can be eliminated once engaged with a lineman, but can show starter-type ability if he makes a good decision and reads the play. An inconsistent player.

"

Projected Rookie Impact:

His experience may be attractive when considering him for playing time, but I think Shelby is better off taking it slow in 2012. He seems to possess a high ceiling in tandem with a bust potential.

This is a player who is better off on a practice squad in a "redshirt" environment. Allowing him the time to transition to the NFL and likely to a new position would also probably be best.
