Biography: Three -year starter at right tackle awarded varying degrees of All-Conference honors since his sophomore season.
Positives: Tall, fluid offensive lineman who moves well on his feet. Quickly sets up off the snap, stays square and then seals defenders from the action with good body positioning. Fast out to the second level, nicely redirects to linebackers and shows ability blocking on the move. Fights with his hands throughout the action, blocks with good leverage, and plays with great explosion. Makes effective use of blocking angles and jolts defenders with good hand punch. Easily adjusts to defenders and effectively picks up blitzes thrown by opponents.
Negatives: Must improve the strength of his base, gets minimal movement run blocking and struggles to finish blocks. Better-than-average skill sliding out to protect the edge, yet he still must improve his overall pass protection skill.
Analysis: Marinelli has been a productive college tackle and is a prospect with good size as well as upside potential. Lacking the strength to play on the edge, he is better off inside at guard for a zone-blocking system. Marinelli may need time to physically mature, yet he is a solid developmental prospect worth the investment of a late round choice.
