Source: Patriots work out Ryan Schraeder

The New England Patriots have one of the top offensive tackle combinations in the NFL with Nate Solder and Sebastian Vollmer. But that hasn't stopped the reigning AFC East champions from searching for depth in the NFL draft.

A source tells ESPN.com's AFC East blog that New England recently held a private workout with Valdosta State offensive tackle Ryan Schraeder. He is a big and athletic small-school prospect who has the potential to develop with the right coaching. Schraeder, who is listed at 6-foot-7 and 304 pounds, is considered a sleeper because of his lack of experience.

Schraeder has an interesting story. He grew at an enormous rate in high school and college, but didn't play organized football until three years into college.

He played one year at Butler community college and one year at Division II Valdosta State -- and that was enough to get noticed. In addition to the Patriots, Schraeder also worked out with the Atlanta Falcons.
