What sold me, oddly enough, is Hard Knocks. His personality and smarts swayed me. I thought a lack of instincts AND a language barrier spelled doom for him. But, he's a VERY bright guy. A few times other teammates have commented to him "you have no idea how strong you are, do you?" on the show.
His tape was awful. He looked clueless. But, you pair his tools and smarts with a year or two under Zimmer? Sky's the limit, IMO.
