David DeCastro put together a strong Pro Day on Thursday as the Stanford guard put together a strong day of performances. He was as big as advertised, but more importantly, he showed plenty of athleticism and explosiveness in his various position drills. However, his most impressive moment on Thursday might not have even come during his workout. Take it away Doug Farrar:

Mancrush on David DeCastro grows -- at a cafe with @RobRang after the Pro Day, and we saw him jogging by. AFTER his Pro Day. Total badass.

During his Pro Day, DeCastro's meeting with the Cincinnatti Bengals dominated the headlines.

Teams in need of offensive line prospects got a two-for-one special as they were able to see offensive tackle Jonathan Martin workout alongside DeCastro.

Lions OL coach George Yarno was 1 of about 8 OL coaches at Stanford pro day today. OT Jonathan Martin & OG David DeCastro 1st-rd prospects
